1315, 26 May 1315 – 14 October 1318 Invasion of Ireland by Edward de Bruce, (last battle won by Sir Milo de Verdon and Sir John de Bermingham) The other Verdon's and their men were reported as being part of that battle. http://what-when-how.com/medieval-ireland/bruce-edward-c-1275-1318-medieval-ireland/
The "their men" may have included Thomas Boyt who was with the de Verdons in 1312 and released from the Dublin Castle to fight the Scots with de Verdon. They went to England first but return to Ireland to protect their home lands in Co. Louth and Meath.
