You Probably already have this information, but, I thought since you were trying to go from 1782 you would like this stuff from the books I use for my genealogy. I am not related, I just decided since I had the books they should help more than just my families.
Let me know if you would like the rest of the information on these baptisms/births. I also checked the following books for Lantz/Lentz
Berks Co. Records 18th Century Vol. 1 and 2 (some lanz/lantz/lentz,
Hans,
Sebastian, has one John George b. 1753, I didn't think this was yours so I didn't include it here)
Lancaster Co. Pa Church records Vol. 1 to 5
Trinity
Luth. Ch. Records, Lanc. Co. Vol. 1 and 2
Following from Early Church
Records of Leb. Co. Pa. by F. Edward Wright:
If you need the rest of the information I will supply it as I have the book:
1774 George and
Rosina had dau Susanna
Catharine bapt. no birth date (St. Paul's or Klopp's Ch.)
1775 George and
Rosina had dau Juliana (St. Paul's or Klopp's Ch.)
1775 George
Lentz and wife
Rosina were sponsors to the bapt. of A. Rosine
Mayer (
Moyer) d/o Henry and
Julianna (St. John's Union Ch, Fredericksburg)
1780 George and
Rosina had son J. Henrich. (St. John's Union Ch, Fredericksburg)
1782 George and
Rosina were sponsors to bapt. of J. Daniel
Schmidt (St. John's Union Ch, Fredericksburg)
1785 George and
Rosina were sponsors to bapt. of Peter
Schaeffer (St. John's Union Ch, Fredericksburg)
1789 your George
Lentz and wife
Rosina were sponsors to the bapt. of John Philip
Kuntz at (St. Paul's or Klopp's Ch.)
Hope this helps in some small way. Atleast you know until 1789 they were still in the Fredericksburg/Lebanon area.
