What is the profession of Noah Claypole's parents'?

From the text:

Noah was a charity-boy, but not a workhouse orphan. No chance-child was he, for he could trace his genealogy all the way back to his parents, who lived hard by; his mother being a washerwoman, and his father a drunken soldier, discharged with a wooden leg, and a diurnal pension of twopence-halfpenny and an unstateable fraction.
