Laurence may have been descended from the family which held ‘Hawmannyslonde’ in Checkendon, Oxfordshire, in the 1330s, although the property known as ‘Hawmanysgrove’ left the family’s possession before 1394, when it passed to John Rede† and his wife.
At the time of his elections to the Parliaments of 1422 and 1423 Hawman was an alderman of Wallingford, and he subsequently served at least three annual terms as mayor. During his mayoralties, on 15 Apr. 1425, 1 Oct. 1427 and St. George’s Day 1432, he conducted the parliamentary elections in the guildhall.
Hawman was acquainted with other prominent members of the local gentry besides Wolf. In June 1428 he was a witness to a conveyance of land in Clapcot to Robert James* of Boarstall, and at Michaelmas following he attested a charter by which the manor of Sotwell near Wallingford was transferred from Thomas Poynings, Lord St. John, to Thomas Chaucer* and his feoffees.
