Annette, thank you for your reply and suggestions.
I've been looking since 2005 for some hint on these 3 brothers. So far nothing credible.
I have worked on IrelandRoots and burned up some money there -- nothing that looks promising. But will keep on checking back as there is always the chance for new records/opportunities that will present themselves. Tho' in 7 years, there has been little found that has been "new".
I don't see likely writing a polling letter blindly to Fannings currently living in Irelamd - a rather blatent violation of privacy -- rather, hoping there will be someone who has interest and will find the posting and reach out if they have interest and are looking for missing people in their ancestry. But, that's just me.......
Thanks again for your help!
