Hello. I just emailed to you somemore newspaper items. They explain why Austin J. Carter, Sr's wife in the 1900 census is "Annie J" born Ireland (Marion Varney's mother) and his wife in the 1910 census was "Mary A." born New York.
You will read that Austin & Annie married June 15, 1885, separated June 24, 1905, Austin remarried a Mary A. (?????) Fogerty and Austin died about Oct 1922.
