I'm tracing my Husband's family tree right now and so far have (which may or may not be correct, still looking) (also, am not listing all of the children had by each married couple, just the main ones that follow my husband's family tree):
Levin Mears (1801-1888) and Rebecca Hobbs (1810-?) had a son, David James Mears (sept.17,1819-mar.1,1888).
David James Mears married Mary A Davis (1836-1872) and they had a son, James Elexander (Baty) Mears (July 4,1872 - Jan.17,1952).
James Elexander Mears married Nancy E Cook (1869-July 1,1900) and they had a son Henry Milton Mears (feb.13,1891- march 4, 1976).
Henry Milton Mears married Annie R Blackman (no info on Annie yet) and they had a daughter Lottie Mears who is my husband's great grandmother who passed away several years ago.
