Re: Letterkenny Sweeneys 1876
sorry to have confused you Ralph. As you know this type of research is a work in progress.
Since that post I have found my G-gradfather's birth information:
James Langan, DOB Jan 09, 1876. (he must have changed his name back to his mothers at some time)
Mother, Mary Sweeney, Magerhaboy, Leck, Donegal.
Father, Patrick Langon, (Place?)
Sponsor, Grace Sweeney (relationship?)
I will register, thanks for that tip.
