Married in 1651 to Priscilla (died 1676), daughter of Luke Cropley, a City lawyer and brother of Sir John Cropley, Sir Robert and Lady Geffrye had no children.[6]
On his death Geffrye left about £10,000[7] divided in legacies to friends, relatives, hospitals and clergymen's widows, and in establishing certain trusts under the charge of the Worshipful Company of Ironmongers. A service was to be provided twice daily in the church of St. Dionis Backchurch, a school to be maintained at Landrake, and the poor of St Erney and Landrake to be relieved.[2]
The remainder was dedicated to 14 almshouses, mainly for widows of ironmongers, being constructed in 1715 at Shoreditch. These buildings were sold in 1910 and now house the Museum of the Home (formerly the Geffrye Museum), which has displays scenes of domestic life from 1600 to the present day.[8][9]
New almshouses were built at Mottingham in Kent, sold in 1972 to the Greater London Council.
Sir Robert Geffrye's Trust continues to maintain two almshouses in Hampshire – one at Hook, built in 1976 and enlarged in 1987, and one at Basingstoke that opened in 1984; they give sheltered housing to 125 retired people of limited means.[10] There is also a Sir Robert Geffrye's School in the village of Landrake, Cornwall.[11]
