I can find no proof that immigrant Peter b. 1727 was ever in Lincoln Co. TN. One researcher (not on line) found that immigrant Peter died in Bethel Township, Berks Co. PA in 1787. To me, it looks as if 1752 Peter b. in Bucks Co. s/o immigrant Peter b. 1720's Germany is the one that came to Lincoln Co. ca. 1818 with his son Peter Jr. and the one that lived to be "old" in Lincoln Co. (listed in the 1830 census, 70 - 80). He also seems a more likely candidate to be the father of Jacob, Samuel, Henry, and Peter Jr. (born in the 1780's - 1805) than immigrant Peter. Do you have a record of immigrant Peter (b. 1727) having been in the Revolutionary War or having been in Lincoln Co.? I've only been able to find Peter Sr.'s (b. 1752 s/o immigrant Peter) record. Gale
