Careful: his son who is also named Jacob is the signing declarant of this guy's wife's death record in 1842 (confirmed by age). But I can't find this guy's death in Steinseltz in 19th C. on Bas-rhin.fr.
I scoured the early 1750s on Bas-rhin.fr, didn't find him there. Not sure there were any Bieglers in Steinseltz then. Maybe he was born somewhere else.
