@Ashtone 1870 Census - James age 35 and Rebecca age 27? It could be them, yes. George was about to be born - not sure what day the census was taken as it's blank on their page. Must go back and look at pages before/after. Retail Liquor Dealer - yes.
I have a James and Frank McNally on the 1900 Census - it's a terribly hard to read entry, but it's the last two rows on the image. I don't know what the street is supposed to be - it was transcribed as Casher Street, but I checked a map and the historical street index of Philly and there's no Casher. It could be Castor Avenue, but I don't think that's anywhere the other streets on the Census page - N. 7th, N. Marshall, and Franklin streets.
