Both sets of grandparents divorced and some got remarried.
Grandpa Gorman Donald
Grandpa Arminta (pronounced Are-men-tah, not sure what origin, German perhaps?) Middle name Ann.
Arminta remarried Robert (I don't know his middle name, he is just my grandma's husband), and he goes by Bob.
Gorman did not remarry and has since passed away.
Grandpa Norman Herbert
Grandma Doris May
Grandpa Norm remarried Linda (I don't know her middle name).
Grandma Doris remarried Thomas (I don't know his middle name), and he went by Tom. Doris and Tom have since passed away.
My husband's grandparents (and great grandparents) are:
Grandma Laura (she was not given a middle name and when she married turned her maiden name to her middle name) and Grandpa Dean Clark LN.
Grandpa Alma Scott (goes by Scott) and Grandma Alice Noreen (goes by Noreen)
Great Grandma Cora and Great Grandma Lenna are his great grandmothers that are still alive. I don't know their middle names.
