Johan Heinrich Sein

"In 1805, John Sine, Jr., son of John (Honis) and Anna Sine, sold his father’s plantation, it being “all the lands where said John Sine now lives.” The purchaser was Maj. George N. Holcombe (1747-1811), who, at the same time, sold to John Sine a lot of 16.7 acres where the Boarshead Tavern stood." see: https://goodspeedhistories.com/the-haddon-tract-part-one/#more-17086

continuing: "Sine did commence operation of the tavern because in 1806, the year he died, the tavern was identified as “John Sine’s Tavern.”13 If I have the right John Sine, he was 72 years old when he died, a little ancient to be running a tavern. He died without writing a will, despite a sizable inventory of $1,016.27. Administrators of the estate were James Gregg and John Robbins. "

His son or grandson may be 'John C. Sine (1822-1902) who we see married Elizabeth Horn and had at least two children:

1. their daughter Mary Ann Sine married John Sergeant, December 24, 1867. She died in December 27, 1871

This lineod descent would be logical for Johann Heinrich only had two brothers: William & Adam.
# William did not have a son John

1. Adam is said to have moved out of state
