Baron Grey de Wilton

Burke's Peerage[1] notes that the June "assembly in question is not now recognized as a bona fide Parl[iament]", but that Reginald had earlier been summoned to the "assembly called a full Parl[iament] of 29 May 1290".

This branch of the Grey family of aristocrats was based at Wilton Castle on the Welsh border in Herefordshire.

Wilton Castle itself passed from the family when the 13th baron was forced to sell it to raise his ransom after being captured in France.

His two sisters would have been his co-heiresses but for the attainder; one of them, Bridget, married Sir Roland Egerton, 1st Baronet, and they were ancestors of the recipient of the second creation below.

The latter titles were created with remainder to the second and younger sons successively of his daughter Eleanor, wife of Robert Grosvenor, 1st Marquess of Westminster.
