Rainbird's first marriage was in 1926, to Eva Warner, and they had a son and two daughters. In the 1950s, Rainbird bought
Whichford House in the village of
Whichford,
Warwickshire, from the
Church of England for £1,400, after it had ceased to be used as a rectory. His wife Joy planned and planted the garden with the assistance of plantsman and designer, James Russell, and it was featured in
Country Life. Later in life, he lived at The Old Parsonage, Church Street,
Moreton-in-Marsh, Gloucestershire, and 45
Bramerton Street,
Chelsea, London. ==References==
