I just want to thank all who have been contacting me about the my family tree. One big challenge is that my grandfather Arthur G. Christensen and at least one of his brothers changed the spelling of their last name to Christensen from Christianson. I have yet to learn why.
I have been in contact with a number of second cousins I've not seen since I was a child, or worse, have never met. With help they've been providing, I expect to be able to release an update to the the family tree to the Internet soon.
