Bobbie: Elizabeth was born to Philip and Magdalena (Georg) Sponheimer on March 22, 1761. Her siblings were Anna Margaret (b. Oct. 26, 1759); Frederick (b. Sept. 1, 1765); John (baptized May 15, 1768); Philip, Jr. (b. c. 1771); Henry (b. c. 1775); Adam (b. c. 1777); Jacob (b. c. 1778). After Philip died in 1806, Magdalena lived with daughter Elizabeth until 1809, then with son Jacob until she died in 1820. Jacob had apparently changed his last name to Spoonamore at some point.
There's more information in "Sponheimer Kindred" (A book from 1975 that I'm trying to locate for several of our kin - I'll post that info about the book at GenForum as soon as I find out anything. It's apparently being updated by someone).If you'll send me your address, I'll copy the several pages pertaining to this part of the family for you (including an inventory of Magadalen's possessions when she died).
