I have made an assumption that Adelbert is a son of Wiliam & Emma, because he and his family are living next to them in the 1910 census. They are at Red House, Cattaraugus Co., NY. Adelbert & Hattie have four children and a stepson (Lee Hall, 16) in the household.
In the Federal Census of 1930, Delbert & Pearl R. Remington, ages 53 & 35, are living at Red House, Cattaraugus Co., NY. They have eight children in the household. The oldest, Halsey D., 21, is from Delbert's first marriage. They are living next to Williwm W. & Alice F. Remington, assumed to be Delbert's brother and sister-in-law.
