Hello; William Rodger Stevens was the son of Charles and Beatrice Stevens. Charles was from Maine or Minnesota different censuses disagree), and Beatrice was from Mexico. In 1900 they appear in the census for Graham Co. AZ, and Beatrice indicates that she came to the US in 1882, about four years before William R was born. In 1910 William is married with wife Elizabeth and a daughter named Catherine, born about June 1908. In 1920 they have MAry and Rodger, both born in Ohio (Mary is 5 and Rodger is 3 10/12, which puts his birthdate somewhere around March 1916. There were no other children in 1930. William was a mining engineer for a copper mine in 1910, and was a civil engineer in 1920 (no employer indicated). In 1930 he was an engineer on the state highway, and his daughter Katherine was a school teacher. Hope this helps to find a link to your family, or to help you to identify the family.

best wishes
