Hi Ronald, I was just reviewing the messages and noted your entry. What else do you know about your grandfather Ivan. I have an Ivan L. Clouser in the 1930 U.S. Federal Census > Ohio > Stark County> Plain Township> District 119 > Sheet 36A. Ivan is the 13 year old son of Charles F. and Cora L. Clouser. Ivan has an older brother Harrold S. (age 20). All of these people are born in Ohio. The father of Charles F. was born in PA and his mother was born in Ohio. Both parents of Cora were born in Ohio. I also have a Katharine Clouser, age 53, with a son Lester, age 22, in the 1930 U.S. Federal Census > Ohio > Cuyahoga County > Cleveland City > District 469 > Sheet 7A. Here Lester has a younger sister Garnet. Another Lester (age 31) is with wife Lilly I., age 34, in the 1930 U.S. Federal Census > Pennsylvania > Cumberland County> Lemoyne Borough> District 18 > Sheet 8A. Another Lester (age 12) living with his widowed mother Minnie (age 34) in the 1930 U.S. Federal Census > Pennsylvania > Indiana County > Buffington Township> District 9 > Sheet 4A. Lester has younger siblings Eleanor, Calvin, and Luella. The final Lester that I have is age 17 living in the large family of William and Skella Clouser in the 1930 U.S. Federal Census > West Virginia > Upshur County > Buckhannon District > District 5 > Sheet 1A. This is at least William's second marriage.
If any of this helps, let me know. I have not yet put this information on my website, it is just in my notes.
