In the Federal Census of 1910, the family is living at Rochester, Monroe Co., NY. Alvah is a general practice physician. alvah and Anna have two daughters: Mildred A. 5 and Edith A. 3. I am not sure if Edith should be Elizabeth, or if that is her correct name; but in 1920 she is Elizabeth.
In the Federal Census of 1920, the family is still at Rochester. There are now five children in the household.
