Found in the 1920 Census for Monongahela City, Washington County, PA:
Harold Austin PETE age 22, Donald Allen PETE age 13, Mildred Marie PETE age 9, children of MARY PETE age 45,
wife of W.E. Dalby, age 42; all 3 children and mother born in OHIO
This is all the info I have on the Pete family, but do have info on W.E. (Waldo) Dalby.
Hope this helps someone, Ruth
