There's a Job Weaver, chainmaker (born in England), in Lebanon, Pennsylvania in 1900. See household 9 here. He gives a birthdate of September 1856, and immigration date of 1891. He and his wife Maria (also born England) say they've been married 16 years and have had eight children, only four of them still alive. All four are with them, the older two (Ada, 15, and Walter, 10) born in England and the younger ones (Mary E, 7, and Arnold, 2(?)) in Pennsylvania.
