I think I've found direct ancestors who lived in Hunterdon Co. NJ in the mid to late 1800s and feel there is a good chance they were in Bucks Co PA as well. County have been another part of PA but I feel somewhat sure this is the family:
1860 Census - Tinicum Twp., Bucks Co PA
Laubenstine, Jonas age 50 born PA
Laubenstine, Mary age 42 born PA
Laubenstine, Himan age 20 born PA
Laubenstine, Elmira age 18 born PA
Laubenstine, Mary J. age 13 born PA
Laubenstine, Emma age 10 born PA
Laubenstine, John A. age 8 born PA
Thanks in advance for any help.
