Hi Jane,
Would this have been 1951? If so, you are right, but I don't remember you, I remember a boy, possibly your brother, who was 5 or 6 yrs older than me. It was at a farm; we brought the cows in to the barn and took the milk to the dairy, and that is about all I remember. I hope this is the right time and place for that visit you remember. Uncle Bob Slone and Grandpa Greene were father and son; the family resemblance was striking. My wife and I with our young 9-month son, went to visit them in Syracuse in 1967. Uncle Bob and Grandpa Greene came to Michigan and we took them to Marine City to see Mark's father for Thanksgiving in 1965. I think Grandpa Greene said he was staying with someone named Greene in Detroit, but I don't know who that Greene was, but I think it was a nephew.
