It is very possible that the Iowa Death Certificates were kept at that time 1889. Perhaps you could look into that possibility. If they have it, it might cost $9.00 or more, but it will have his fathers name as well as his mother name with her maiden surname. Check here first. I know that the Virginia Paxton's scattered wide and far. Have you tried The World Family Paxton DNA Project? This is always possible to do the Y-chrome DNA test to see if you tag anyone already posted. I will see what I can find in the meantime.
