Windmuller-Heynen Family Tree

The DAR Lineage Book says the wedding took place at New Providence,
New Jersey which isn't very close to Scotch Plains:

Thomas Lenington, (1755-1829), served as sergeant under Capt. John
Nicholson in the Canadian campaign; was promoted ensign 1776; was
taken prisoner and confined fourteen months at Quebec and Halifax.
After his exchange he was employed in the quartermaster's department
and had command of a vessel on the North River. The widow was one
hundred and four years old in 1848 and a pension was allowed her
for over two years actual service as sergeant and ensign in the New
York line. She was married in New Providence, New Jersey and received
her pension in Brooklyn, N. Y.

The 1800 US Census and entries in city directories for 1803 and 1805 indicate that this family lived in Albany. The History of the First Presbyterian Church of Albany, N. Y. shows that Sarah Lenington joined that church in 1805. A city directory for Brooklyn shows the family living there in 1824 and 1825.

The 1830 US Census for New York City has an entry showing Sarah Lenington, as head of a household that included two others, a male age between 10 and 14 and a female age between 30 and 39. Names are not given but by the ages it is possible that the young male was Sarah's grandson, John Edmund Thorne (born early in 1815 and thus -- depending on the date the record was made -- possibly 14 at the time) and that the female was John Edmund's mother, Sarah's daughter, Abigail (born 1793 and thus about 37 at the time).

The 1850 US Census shows Sarah Lenington, born in New Jersey, age 105, living with John E. Thorne and his daughter, Amanda, age 19, and a girl named Abigail Lenington, age 12 (all three born in New York).
