Update: my friend P and Glinny are kin

We are on the mutual quest of finding out what happened to the mysterious grandfather James O'Neill. I have year of birth as 1870 in Westmeath. When he was 18 he married Catherine Jessop in Ireland, I assume in Westmeath, that is where she was from as well.
At unknown point, they moved to US, had Annie. Length of stay was 7 years. returned by 1901, when James Jr was born.
James Sr had left by 1911, as noted by absence in census.
To think a google search brought his all together. I have read through a few pages here on this board and there is so much help available, a great source of information. Very happy to have stumbled in!
