This is the only thing I have on a Curtis Avery during your time period. Abstracts from Wyoming Co. Orphan's Court Records Vol. 1 Avery, Elijah, late of Lemon Twp. 22 Sept. 1856 Petition of Curtis L. Avery, Administrator., mentions children: Volney; Daniel;Elmira w/o Cyrus Squires; Elvira w/o Hiram Jones; Daniel Culver; Sarah w/o Jacob Cross; Elizabeth Fordunn (deceased) leaving child, Susan Avery; John; Curtis L. I do not believe this is your Curtis since he was only 1 at the time of this record. He might be connected though. Most of what I have is pre-1850. Jennifer
