Leitrim-Roscommon

Thanks John and Ed, I found the Rush list on Griffiths Val and when I googled Talbotstown it turned up in Wicklow also, neither got me much further. I also found Mount Talbot in Roscommon but thats pushing it I think. Interesting that link with Dillon family in Talbotstown. There's no family lore as...

An old probably inaccurate, family tree says Patrick and Dillon Rush (brothers) left Talbotstown Roscommon for Dublin c 1870. I can find no talbotstown in Roscommon. Has anyone come across either Rush family or Talbotstown?
many thanks
