Notes: I have found Gittinger also spelled as Gettinger.
Marie Anne Valle's parents were Francois Charles Valle and Julie Lalumendiere; Marie was one of 9 children in this family. You indicate her birth year to be 1843, I found it to be in 1845. [source: The Valle (La Vallee) Family, A Journey Covering Four Centuries, by Betty Valle Gegg, pg 13: d/o Charles Valle & Julie Lalumondier.Marie Anne Valle b. 2 July 1845.]
Marie Anne Valley's grandparents were: Charles Valle born 25 Nov 1748 & Marianne Corset born 24 Mar 1771.
I hope this information is of some assistance to you. Sincerely, Joni VALLEY Stockinger Huntington Beach, CA
