t The family tradition among the descendants of their two older brothers is. "they went to Pennsylvania, or the West, changed their names to Strowbridge, and one of them had a son who was a doctor." There seems little doubt that Justus is the Justus Strawbridge (or Strowbridge) of Columbia county. Pa., whose family record and that of his descendants appear In Mrs. Mary S. Guild's "Strobridge-Strawbridge Genealogy," pages 251 to 260.  By the record there printed, it appears that Justus Strowbridge (as he signed his name), or Strawbridge (as it is printed), (his descendants use both spellings) had, among others, a son Shobel and another son who was a doctor. To letters written by the compiler and mailed with his introductory circular to descendants of this Justus, the Strawbridges of Philadelphia,
Pa., and the Strowbridges of Portland, Ore., families of prominence in those cities, no reply was received.

t His granddaughter Mrs. Sarah T, Beatty (No, 201, xi) was the principal authority for this family register. No records of their births were found in New Jersey,
g Is remembered to have said, "father had six brothers," II.  She told a nephew (No. 376) that her father (No. 135) and a brother came from New Jersey.


Shubael Trowbridge and his brother Absalom seem to be the ancestors of most of the Trowbridges who lived in Morris County.  There is one branch of the Trowbridge family in counties of Columbia, Monroe and Lycoming, Pennsylvania that goes by the ;name of Strawbridge. The origin of spelling, according to Francis Bacon Trowbridge in "The Trowbridge ;Genealogy", occurred when Shubael's son Justus moved to Columbia Co., Pennsylvania. His descendents starting using the name of Strawbridge, instead of Trowbridge. Francis Bacon Trowbridge relates one supposed origin that it was derived from how Shubael Trowbridge signed his legal documents. When he signed "S. Trowbridge", several people did not see ;the period after the S, and they started to spell "Trowbridge" as "Strowbridge. But there are several other descendents of David Trowbridge and Lydia Holmes that went by the name of Strowbridge, notably the descendents of Shubael's younger brothers Absalom in Morris County, New Jersey, Samuel in Frederick County, Virginia.  The same explaination for Shubael has also been given for Samuel, that some county clerk mistook the S. Trowbridge for "Strowbridge", and because of the complexity and expense involved in correcting legal documents, which could have jeopardized land deeds, those branches of the Trowbridge family found it more expedient to adopt the Strowbridge spelling. While that maybe a good explaination for Samuel's family, it doesn't seem to fit with Justus and John, because they used the surname "Strawbridge".  And of this explaination wouldn't fit with Absalom's family, especially the family of his son Chillion, since both father and son's first names began with an "A" and "C".


Shubael inherited 18 acres from his father David, as per his fathers will. It is unknown where Shubael was buried. He was probably buried in the Baptist Cemetery in Morristown, but unfortunately in the 1880s the cemetery was purchased by a developer, and all of the bodies where moved to the new cemetery at Evergreen Road in Morristown. The graves of Shubael, his father David and mother Lydia are probably lost,  as their names do not show up on any lists of those reinterred at Evergreen, compiled and maintained by Evergreen historian Kemper Chambers from cemetery records dating back to the 1850s.

"OK time to get the chains out to measure where Shubael's farm was:

Gunter's chain n.
Surveying a measuring instrument 66 ft (20.1 m) long, subdivided into 100 links (1 rod or perch = 25 links), each link being a short section of wire connected to the next link by a loop. It was long used for land surveying and became a unit of length (80 chains = 1 mile), but has now been superseded by the steel tape and electronic equipment.
[Edmund Gunter, Engl. mathematician (1581-1626)]

The Oxford English Reference Dictionary
You [your name] doe swear by the great name of ye living God that you shall faithfully attend to and discharge your office of Surveyor unto which you are appointed without favour or respect to persons.

The Surveyor's Oath (c1760)
You ____ and ____, Being desired to assist [name of surveyor]. -- Surveyor;
in carying the Chain,Do Swear by the Everliving God
that you will faithfully assist the said Surveyor in his servis and that you
will keep a true account of all Lines on measures by you taken and the
same give up
to said Surveyor at his desire according to your best Skill and ability
So help you God.
The Chainsmen's Oath (c1760)

Gunter's Chain is the most widely known unit of measurement that is universally attributed to the Art of Surveying. It came into common usage about 1700 a.d. and was the standard for measuring distances over 150 years. Until early in the 20th Century, it was universally made of iron or brass links. Because all of these chains were hand made, they rarely measured exactly the proscribed sixty six feet in length. Thus, the surveyor had to use a correction factor when translating his notes into a drawing. In later years, it became the Surveyor's Tape that was machine made and used sophisticated metallurgy to compensate for the small (but measurable) effect of temperature on the length of the tape. These chains are commonly found in both the full (100 link) and half (50 link) lengths.

The Chain Winder
This wrought iron device was frequently used in the field to keep the chain from tangling, thus speeding the process of measuring distances.

Chaining Stakes
These stakes come in many sizes and shapes. Their main function is to aid in holding the chain in place while the chainsman makes a change in direction. They can also be used to identify temporary locations the need arises.

Gunter, Edmund (1581-1626), was of Welsh extraction, but was born in Hertfordshire in 1581. He was educated on the royal foundation of Westminster school, and in 1599 was elected a student of Christ Church, Oxford. After graduating bachelor and master of arts at the regular times, he took orders, became a preacher in 1614, and in November, 1615, proceeded to the degree of bachelor in divinity. Mathematics, however, which had been his favorite study in youth, continued to engross his attention, and on 6th March, 1619, he was appointed to the professorship of astronomy in Gresham College, London. This post he held till his death, which took place on 10th December, 1626. With Gunter's name are associated several useful inventions, descriptions of which are given in his treatise on the Sector, Cross-staff, Bow, Qua drant, and other Instruments. He had contrived his sector about the year 1606, and written a description of it in Latin. Many copies were transcribed and dispersed, but it was more than sixteen years afterwards ere he allowed the book to appear in English. In 1620 he published his Canon Triangulorum, a table of logarithmic sines and tangents (extended to 7 decimal places) for every degree and minuteof the quadrant. In later editions an account of the general use of the canon is prefixed, and Brigg's logarithms of the first 1000 numbers are appended. There is reason to believe that Gunter was the first to discover (in 1622 or 1625) that the magnetic needle does not retain the same declination in the same places at all times.By desire of James I, he published in 1624 The Description and Use of His Majestie's Dials in Whitehall Garden, the only one of his works which has not been reprinted. He introduced the words co-sine and co-tangent for sine and tangent of the complement, and he suggested to Briggs, his friend and colleague, the use of the arithmetical complement (see Brigg's Arithmetica Logarithmica, cap. xv.). Other of Gunter's practical inventions are briefly noticed below. 

Gunter's Line, a logarithmic line, usually laid down upon scales, sectors, etc. It is also called the line of lines and the line of numbers, being only the logarithms graduated upon a ruler, which therefore serves to solve problems instrumentally in the same manner as logarithms do arithmetically.
Gunter's Quadrant,an instrument made of wood, brass, or other substance, containing a kind of stereographic projection of the sphere on the plane of the equinoxial, the eye being supposed to be placed in one of the poles, so that the tropic, ecliptic, and horizon form the arcs of circles, but the hour circles are other curves, drawn by means of several altitudes of the sun for some particula r latitude every year. ; This instrument is used to find the hour of the day, the sun's azimuth,etc., and other common problems of the sphere or globe, and also to take the altitude of an object in degrees.
Gunter's Scale (generally called by seamen the Gunter) is a large plane scale, usually 2 feet long by about 1-1/2 inches broad, and engraved with various lines of numbers. ; On one side are placed the natural lines (as the line of chords, the line of sines, tangents, rhumbs, etc.), and on the other side the corresponding artificial or logarithmic ones. By means of this instrument questions in navigation, trigonometry, etc. are solved with the aid of a pair of compasses.
