Ellenbergers are an elusive bunch. I'd like to have this family figured out myself.
In the 1860 Census, French Twp., Adams Co., IN on page 186 we find Abraham Elebarger age 48, with his wife Elizabeth age 57. Both were born in Switzerland. Another source shows that the age difference is correct. Elizabeth died in 1870) and her maiden name was Müller.
Children were: Valentine age 22 born in New York
Eliza age 21 born in Ohio
Louisa age 18 (?) " "
Henry age 17 " "
Caroline age 16 " "
Frederic (?) age 14" "
Peter age 13 "
In the 1870 census, French Twp., page 19, at the bottom, you'll find Abraham Baumgartner. His wife was Caroline Ellenberger (age 27). Living in their home was Frederick Ellenberger (age 24). Next door lived Henry Ellenberger and wife Catherine. (he was age 26).
There is one reference in another source to Mt Eaton, Wayne Co.,OH as a birth place. You might try that 1850 census, although many of the Swiss came in after 1850.
I do have some additional information, if you'd like to contact me off list. By the way, Valentine was a common name among the Swiss. . . and it could easily be shortened, or mispelled to Faldine.
