Perhaps you don't have access to US censuses?
In 1910, there is a 49 year old Amos LORD, widowed, boarder in the home of the Thomas MCEVOY family in Lowell, Middlesex County, Massachusetts. Amos was born in England and his occupation was spinner in a cotton mill. It says he emigrated in 1890 and was naturalized.
So although his age is slightly off I think this is highly likely to be the person you seek.
I will keep looking.
