Something more for you - I found a death record for Albert B. Crocker on familysearch.org - b. April 29, 1844 in Ontario, Canada, d. April 9, 1928 in Yale, St. Clair Co. MI. Parents names on record John Crocker and Hannah Weaver. I also found a death record for Mary Ann Crocker b. March 21, 1852, Ontario Canada, d. April 21, 1928 in Yale, St. Clair Co. MI. Father named John Gingrich on record, no mother's name. As a tip, beware of birth and parent info given on death records as it sometimes turns out to have errors. (The dead person wasn't there to give the info!) Always verify it with other records.
