I'm trying to locate any information regarding my great-grandfather Richard Alexander Avery, son of William Avery from New York. Richard Alexander Avery m. Marie (Mary) Ducharme back in the Great Lakes area. They had four children, Richard (who was born in Prentice, Wisconsin.), Blanche, Olive, and Pearl.They moved to a farm in the Burlington area around the time of WWI. Richard Alexander Avery died in the '40's, but I do not know where.Marie died in the '60's as I recall, in Sedro Wooley. Most of the information I have is sketchy, but if someone could tell me where I might look, it would be appreciated.I keep running into roadblocks. I have checked the Social Security Index, and the LDS.
