Daniela,
Unfortunately, I don't think I can be of much help to you. Although my grandmother,Theora, raised me, I never knew my grandfather, Conrad. That part of who I am is pretty much a mystery to me, which is why I was so excited to stumble across this thread on this site. Imagine my suprise!! If I understand your project you need DNA from direct male descendants. My grandfather's only son was my "Uncle Bud", John Vernon Phy. He died about 4 years ago but left only one daughter.
Any info on the family you could share with me would be greatly appreciated. I would like to have something to give to my children and my niece and nephew.
Thanks,
Connie Eggers
