I believe that the parents attached to Leah and her siblings are incorrect the census of 1850 shows father Michael 1804 but in later census 1806 which in fact is 1807 https://www.findagrave.com/memorial/108804246/michael_wanbaugh
Michael Wanbaugh
siblings are duplicated here also
he was married 2nd to Louise Fisher also name is spelled WaNbaugh with an N not M
I have also attached her marriage record which shows Michael Wambach and Mary Wambach but it is translated incorrectly
also some of Leah's siblings born when this Mary was in her late 50's
