'WILLIAM HORTON born undoubtedly at Mowsley probably before or by 1360 as he was of majority age in 1381; died after 1390 at Mowsley, Leicestershire; married Joan (-) before 1381.
William, probable son of William, certainly a direct descendant, is of record in the Mowsley Poll Tax of 1381. With wife Joan he is shown as a land-holding resident, paying a tax rate of 21d [citing Poll Tax for Mowsley, 1381, from Lay Subsidy 133/35 in Leicester Public Record Office; cited by Horton-Smith (1943), 9]. The fact that this is the lowest tax rate of any Horton in Mowsley in that year suggests that William's father still lived and occupied the family property.'
