I guess this is stuff you have already seen, Nell, so I've not spent ages with it!

I did find someone listed as "Callaching Mc Carthy" on Ancestry in 1871, who is likely this man who died in 1877. I tried to make him a waggoner, but he insists on being a greengrocer!
Only picked him out because of the area he lived in and because his age seemed reasonable. He and his wife have put their counties of birth o the census too
