Hi Paul Gilbert: Please contact me as I am your cousin and wondering how you are advancing with your family history. I would really like to get more info. about your dad and grandfather. I have a picture of Robert Louis in his 20's and the big white house in Omaha?, Nebraska with a lady on the porch and a little girl with a doll buggy on the sidewalk. I also found your dad listed in the American Who's Who in about 1980.
We have relatives in the Winnipeg area as well as Ontario. There was also an uncle Sylvester? who lived in Santa Barbara. Question: Why is your surname not PRESTON (not a snoop but a genuine genealogical question).
