I have 2 David LEGLERS: The furthest back was married to Susan VOEGLI whose son is Joachim m.Marg. SCHINDLER whose son is another Joachim m. Anna CLAUSER whose son is David m. M. ZWEIFFEL. Maria Madgelena LEGLER is the daughter of Joachim and Elsbeth STREIFF. Maria m. Michael SPEICH in 1823 in SWITZERLAND and thier son Joachim emigrated to the US around 1850. I also have 2 HEFTI sisters(Maria and Verona) from 1608 who both married Abraham SPEICH in 1629. I am sorry I don't have more accurate dates. I do not have a Barbara LEGLER so I can't help you there. I have many names in my Swiss Heritage so if you come up with any let me know. They are: SPEICH, STOCKER,LEGLER, (W)PERREN,LUCHSINGER,STREIFF,ZWEIFFLE,VOEGLI,NIGG,CLAUSER,ZOPFI,BLESI,WEBER,BETCHEN,MUELLER. Hope your search goes quickly and smoothly.
