Avery IN New Jersey USA

My grandfather was Harry Avery born in Maine, 1881.Last known address was Bank Street, Newark, NJ. He was listed, as a painter, in the 1912 Newark City Directory. To date I have been unable to find any more information as to what happened to him. He married my grandmother,Margaret Hanratty,{born in Ireland 1889} in Attleborough, MA, April 1908, at the Methodist Church on Sandford and Main Street. I have a copy of the marriage certificate issued by the Town Clerk at Attleborough. Plase help if you can. Thanks, Margaret Robinson.
