After being the only teenager in the genealogy room at the library for years, I married a Garvie and hit some dead ends. Every question I ask, his parents say, "We should really know that, but we don't."
What I do know.
Glenn Vernon Garvie b. March 2, 1917 in rural Quinlan, OK, d. Feb. 10, 1983 in Alva, OK. m. Louise Annabelle Osburn on Oct. 29, 1938. They had three sons, all living. Vernon was an accountant for Star Lumber in Alva, OK and once owned a restaurant in Mooreland, OK.
Glenn's father, Will Garvie, was a farmer and a part-time Assembly of God minister. He was 6'3" (an important fact for a family of short people.) He married Ethel Finley. I actually have a picture of this man.
Will's father is supposedly William Garvie. His wife's name was Mary.
As you can see, this is not very good. I can not even find out where Will, Ethel, William and Mary are buried or any locations for them.
