Hi Mike,
Perhaps maps of geographical distributions at the European level of testers' EKAs in a haplogroup, such as the following 3 which, if I am not mistaken, concern you (upstream haplogroups), would be of any use to you?

This can potentially give you an idea of ancient migrations followed by your patrilineal ancestors, but unfortunately it should not tell you much about your ancestor who migrated to the USA.
Data presented are taken from FTDNA's "SNP Map" tool. The 2nd percentage given is a correction for the bias stemming from the fact that not all regions of Europe are tested at the same frequency. However, some uncertainty remains on these results (question of probability - not assessed here). These maps are intended to be used in conjunction with FTDNA's Discover - Time Tree tool ans aDNA results. I could provide you with more information on reading these maps, as well as their limitations, if interested.
Best regards,
Ewenn
