Hi Jason,

Under Le Waleys or Wallis, of Burgh-Wallis, Yorkshire,
Stephen le Waleys born abt. 1305 of Helaugh, Yorkshire and died 1347 of Burghwallis, Yorkshire.
His wife @ Annora de Umfreville (my 20th great aunt) is shown as the birth abt. 1307 of Castle, Prudhoe, Nothumberland.
Would these help with your dates?
Kind regards
