He made some efforts also to build up a network of family alliances in Ireland: his brother George, to whom he was close, married Anne Ruish, sister of Strafford's great friend Eleanor Loftus, and his sister Elizabeth married James Dillon, Earl of Roscommon. Roscommon, unlike most of the Anglo-Irish nobility, remained staunchly loyal to the King during the Civil War. His son Wentworth Dillon, 4th Earl of Roscommon, was named for his distinguished uncle, and grew up to be a poet of some distinction. Strafford seems to have taken some interest in his nephew's education, and he spent part of his childhood at his uncle's Yorkshire home.
