I thought that you would have been automatically notified by Genforum about the posts on the other boards. As for Alien Registration Form: http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=6f2a4154d7b3d010VgnVCM10000048f3d6a1RCRDhttp://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=6f2a4154d7b3d010VgnVCM10000048f3d6a1RCRD Sometimes because the name is common, the research can be difficult and thus you need to know his precise place of birth. Care to share his correct spelling of the surname? I do not have a paid subscription to Ancestry so can not help much but I can look at the document if the handwriting is in question. You can locate a site even, if it no longer exist with http://www.archive.org/index.phphttp://www.archive.org/index.php just to see what the website contained.I see that yugoslavroots no longer works.I will go back and look on the sites that you say are not working. I might have typed them wrong.
