“The coat of arms for this family is identical to the arms of the parent house with a crescent for difference, indicating descent from a second son of Byrom. This coat of arms had been confirmed to the Byroms of Salford by Sir Richard St. George in 1613 and used by that branch as early as 1558 and later by the Byroms of Manchester. (Raines)”
