Re: Cornelius & Penelope Coughlin VA>WV>IN
For Cor(nelius) Coughlin B 1833 +/- 5 yrs, Co. Cork, with the father's forename unknown, I found 4 rcds: 1830, 1831, 1832, and 1836.
For Penelope Jordan M 1859 +/- 5 yrs, Co. Cork, I found 0 rcds. I got the same result when I searched for her B rcd in all Ireland - nothing within a relevant range. This suggests either Penelope's rcds didn't survive, or she was born and married in America.
For Tim(othy) Coughlin B 1859 +/- 5 yrs, somewhere in Ireland with a father forenamed Cornelius, I found 0 rcds.
Sorry for the negative results. Hope this helps. Good luck.
