if you are getting info from the mormon church, that should be sufficient. it's the people that post their family tree you can use as a guide but it may not be right until you get the documentation to confirm it. i have found the helms from fulton are all related. my family is also from the fulton area. i grew up in a town about 10 miles away from there. if you go to findagrave.com you can search the graves of family members in the counties of Clinton, Ionia,Gratiot and Montcalm, here in Michigan. There is a Charles and Mrs Charles Helms buried in Portland Cemetery in Ionia county. Her name is Mary. The other Mary Helms in the cemetery is not Charles wife. They had a stillborn child, Clifton buried there also. I discovered this last night. but, i think that charles is the son of David Helms. it makes it hard as a lot of names are repeated in generations.
who was your grandpa, charles? where did he move to? there is a lot of history for helms and they are some of the original settlers in michigan and in the united states.
