John Foster of Dunleer

He was the son of Colonel Anthony Foster of Dunleer, whose father Samuel had come to Ireland from Cumberland. He held the position of Mayor of Dunleer Corporation.

He married in 1704 Elizabeth Fortescue, youngest daughter of William Fortescue of Newrath, County Louth, and first cousin to William Henry Fortescue, 1st Earl of Clermont. They had six children:

• Alice Foster who married Thomas Bolton.^[2]
