Hi Paul, Here is what I know about Marshall Abbey and family: Marshall was born in Canada. He died in Michigan March 5, 1896. He and his wife had 3 children: Sarah Abbey who married a Simmonds; Jerome B. Abbey who was born January 9, 1863 or 1864 in Michigan; Shylor Abbey. My husband is a descendent of Sarah Abbey Simmonds and her father Marshall Abbey. I just found a distant cousin last week and he is a descendent of Schuyler George Abbey and his father Marshall Abbey. He just started and his sources are from the older family members. Here is what he knows about Marshall and family: Marshall was born on September 13, 1839 in Kingston, Ontario, Canada. He died in Marlette, MI. Marshall married Gracia Hagar who was born on Sept. 19, 1839 in Dresden, Ontario. He knew of only one child: Shuyler George Abbey, born in 1858 in Dresden, Canada, and died in 1924 in Denton, TX. I was able to find Gratia J. Abbey and Jerome B. Abbey in the 1900 U.S. Census. They were in Marlette Twp., Sanilac Co., Michigan. Gratia was head of household, widow. One bit of helpful info: Gratia immigrated to U.S. in 1859. The Shuyler George Abbey, born in 1858, had one child listed: Roy Shuyler Abbey.
