Alan, I am Wanda (Krewson ) Zinn and my grandpa was Garland Allis .I think I have the information you are looking for about Al Everett Allis folks. I will have to look it up as I did some work on The Allis family. I have then back to around 1600 I think. Give me a few days to look it up. We always called him uncle Everett.
