OK, you are on my tree :) In fact, I met your mother and your daughter in Willmar in 2005 at the lunch when we first met up with Ted and Sylvia. Ted and I have been in contact since, and yes, I knew of his passing.
I will be happy to provide information on John/Johan.
Please send me an email at: firstname.lastname@example.org
so I can send your the info in the format you want.
