Yes, it sounds like we might have a match here. My grandmother was Helen Marguerite Yates, daughter of Laura Belle Reagan and Garland Hurst Yates. She was born in Haskell, OK as were a couple of her brothers, I believe. Before moving to Muskogee county, Laura and her husband lived in Neoshoe, Misouri as did her parents and brothers, George and Aaron. It's possible that the entire family went to Oklahoma at the same time. Laura said her mother, Harriet, died in Oklahoma in 1925, but I've never been able to find any record of it.
