Danny, you thanked me for telling you your grandfather had a "sponsor" to emigrate to Iowa. I did not say your grandfather had a sponsor to emigrate to Iowa! I didn't even know your grandfather lived in Iowa.
Here's how this mistake started. You were looking for a possible immigration of his brother Christian Aage Christensen to USA. You weren't sure Christian had immigrated, but you wondered. I found an emigration record for a Christian Christensen of the right age, who had lived in the right place (Vester Flakkebjerge in Soro amt), who was emigrating to Iowa.
When I said I found a "candidate" (I did not say "sponsor") for Hans Peter Hansen in Iowa, I meant the US census showed a man named Hans Peter Hansen, of the right age, who might be your grandfather, and he was living in Iowa. I was looking for your grandfather in the USA.
Why did I do that? Most often Danes who immigrated went to the place where a friend or family member had gone before them. In this case, Christian might likely go to the place where his brother Hans Peter Hansen was living. So I was asking you: Is Hans Peter Hansen in Iowa? If yes, then it is the more likely I found the "right" Christian Christensen immigrating (but still not proved).
I hope this clears up the misunderstanding about the "sponsor." I didn't mean to be confusing when I first wrote about the "candidate" for Hans Peter Hansen. I should have just asked you straight out: where did Hans Peter Hansen live?
