It would appear that Abraham's marriage to Hannah was his second marriage and that he married first Charlotte Boxall. She died and he was left with two young daughters Maria and Sarah (you will need to get certificates or check the parish registers of Greywell and possibly Odiham to prove or disprove this, since the 1841 census does not state relationships).
On the 1851 census the two girls are in a Union School (so it would appear they were sisters), as in the poor law union. This means they were chargeable to the local poor law union rate payers who were paying for their board and up keep. For this to happen it would appear that Abraham sometime after the death of his wife seems to have deserted his children. His mother Ann was dead - his father John in his late 50s. The children were placed in the workhouse system.
Since Abraham was able bodied and therefore could support his children, the local poor law union would be interested in his whereabouts since he owed them for the maintenance of his children. He could be fined and gaoled in the petty sessions for non-payment if found.
