My husband's Heritier ancestors lived in Pinache. His great grandfather came to the US in the 1880's. His gr-great grandfather was Johann Peter Heritier, born 05 Oct 1828 in Pinache and died 06 May 1904. Is there information about this Heritier line in your book? I found one source that traces Johann Peter's ancestors back to David Heritier, b 09 Feb 1766, son of Pierre Heritier and Marie Ayasse, and would like corroboration. Thank you for any assistance or advice.
