I was looking at the 1930 census records for Mt Clemens and found the following. There is an Albert A. Shorkey listed as a step son of Stephen E. Lytle and Minnie A. Lytle. His age in 1930 is 23 and his occupation is lineman for the telephone company. That sounds like it could be your grandfather. There is also a Floyd Shorkey married to Theresa Shorkey. Floyd in 1930 is shown as being 29 years old and Theresa is shown as being 28. They have an 8 year old son in 1930 who is 8. His name is Charles E. Shorkey. Do you think Floyd might be an older brother of your grandfather?
