John E. Mansfield/Bridgman/Gilkerson Families

I am researching the Bridgman family that came from Tavistock, England in 1767 (John Bridgman) and moved to Canada as a UEL. Most of the descendants are still in the Ontario, Canada area. I"m also researching the Masnfeld (now Mansfield) family that came from Bohemia and settled in Chicago in the mid 1860s. Anton Mansfeld married Rosa Kolbaba. Also looking for contacts on Charles C. Gilkerson who married Mary Page on October 26, 1873 in Henry County Missouri. They had five children, Jessi b.1879; Bethias b. 1880; Elizabeth (my grandmother) b. 1882; Edward b, 1884; and Ada b, 1886. Any information would be geatly appreciated.
