Re: 1870 census....Anna's occupation is "car cleaner"
Found this little tidbit on Ancestry.
1903 Andrew CARNEGIE has placed on his private pension list $20 month to Mrs Ann MULHERRON of Blairsville, who used to clean cars when the Laird of Skibo was Supt of the division. [haven't a clue what this is]
Possibly Ann was m to John MC GRATH
1860 Indiana Co PA
John 30 Ire
Ann 18 Ire
Bridget ? Ire
John 10 Ire
She evidently resumed her maiden name. Depending on when John died/div/split, it's possible he is Wm's father. John may have been in Civil War.
OK, not knowing too much abt Andrew CARNEGIE, other than being wealthy, I googled .....Skibo is the name of his estate in Scotland, so he is the Laird.
