Thank you so much for your help. This has been such a help!
Just curious though-the 1910 census lists him as 50 and the census of inmates as 62. I know there can be age differences in everything you find and Bridget matches but that changes the immigration year by a lot as well. I just want to know from someone who has been doing that longer if that makes you second guess one of your sources and if that is valid, like the 1910 census I found, or even this? I'm find this a lot as I dive deeper into this and it's driving me crazy, lol!
Also, just for my own reference, did you specifically go looking in this particular census? Or did you just type in a William McNevin and find it?
