where was grandfather William Hedge 1867 born, and where was his sons, Benjamin or Roy T.
born??

In the 1900 census William was living in Kansas City Missouri With his wife Mattie he was 28. In the 1910 census he was in McPherson Kansas With his son Ben. He was 42 and Benjamin was 16. In the 1930 census he was living in Ozark Polk Arkansas With his son Ben with Ben being the head of the house. Ben is 36 with a family and now William is 74. I have been digging.

I need to investigate some of these dates are a bit off.
