What a great name... Are you looking at the 1900 home of William and Isabella Grant in No. Braddock, Allegheny, PA? If so, I notice that Wm and Isabella, as well as Archibald (pipe fitter), are from Scotland. Archibald emigrated in 1895.
There is an Archibald Rolland Peacock, plumber, who applies for naturalization in 1910, with wife Mary; says he arr NYC 1 Aug 1895 on the Furnessia (and there is such a passenger list so naming him). Not sure if the's the same guy, although it's tempting... pipe fitter? plumber?
