I think Helen has it right in that the generation is the right one to connect to our James, Sr., but that its too tentative to say anything other than "maybe" there are connections (although by my standards that's not bad when talking Ireland at this time!).
While there is apparently some suggestion from one McManaman descendant on Achill that our McManaman's in The Valley may have come to Achill from Ballycroy, we have nothing that suggests what decade, or even which century. Its pretty clear it would have been after about the 1650's when they would have fled to Mayo from Donnegal, but beyond that, who knows if they came to Ballycroy before coming to Achill?
For me, the confusing thing about all this is the fact that they all used the same names over, and over, and over. . . (then again, I did the same when naming my kids and used traditional Irish names!)However, it is also apparent that the McManaman/-on variation is mostly from this same section of Mayo, right? So it makes sense they are all related sometime since coming from Donegal. (Has anyone seen McManaman/-on's's from anywhere else?)In any event, since it seems that records going back beyond James, Sr. won't likely be found for Helen and me, and our numerous cousins, I have settled for attempting to discover the general history of Ireland at the time, some of the specific history of Achill, and the McManaman line going back to Donegal and such.
There might be some clues to the types of connections between the Ballycroy area and Achill in two books I am familiar with:One is "Where The Sun Sets" about Balycroy, and the other is "Achill" by Teresa McDonald. From what I remember, the areas are closely related. Also, there were, for a time, McManaman's living on Innishbiggle, an island sort of between Achill and the mainland.
By the way, somewhere along the line I saw a picture of a tombstone of a Mary McManaman, and I think it was in a famous book on Ireland.Was it by Leon Uris?
