If you have them on the 1871 Census, can you please advise his age and PoB ?
Added: do you know if they had sons Elijah & Harry by 1871 ?
If so, they are in Hookagate, Brace Meole, Shrewsbury, Shropshire in 1871.
Sarah Ann says she is from Pontesbury ( a place within the Atcham Regn District) born c1845.
William, born c1839 is from Birmingham - he is a Coal Miner.
Grandmother Elizabeth c1797 is present. She was born in Hookagate (Brace Meol), Salop.
If this sounds correct, we can go back to an earlier census to find more.
