My Kears in Pennsylvania were:-
George Kear born 11.4.1829 in Forest of Dean, England
married Lowetta Williams in West Salem Township, Mercer, P.A. on 11.12.1851
These two had 13 children and ended up in Marshall Illinois.
Do you know who the father was of your Elizabeth Kear because I may be able to help with the English side of your family tree.
