His elder brother, Colonel Simon Luttrell, who was member for the county of Dublin, and military governor of the capital, had also resided in France, and, though inferior to Henry in parts and activity, made a highly distinguished figure among the adherents of James.

The other member for the county of Dublin was Colonel Patrick Sarsfield.

This gallant officer was regarded by the natives as one of themselves: for his ancestors on the paternal side, though originally English, were among those early colonists who were proverbially said to have become more Irish than Irishmen.

His mother was of noble Celtic blood; and he was firmly attached to the old religion.

He had inherited an estate of about two thousand a year, and was therefore one of the wealthiest Roman Catholics in the kingdom.
