Sir Richard Gardiner (died 19 December 1489) was, in 1478, elected Lord Mayor of London.
He married Etheldreda (or Audrey) (who died in 1505), the daughter of William Cotton, Lord of the Manor of Landwade, in Cambridgeshire, who survived him and married, secondly, Sir Gilbert Talbot, Knight of the Garter, of Grafton, Worcestershire).
By Audria, Gardiner had one child, Mary, who in 1504 married Sir Giles Alington, Knt.
"In his will, Richard Gardener [sic], Alderman of Walbrook Ward, left to Etheldreda or Audria, his wife, his lands, tenements, &c., in the parishes of St.Bartholomew the Less [towards the Royal Exchange], St.Michael Queenhithe, and Holy Trinity the Less, for her life, with remainder to Mary, Lady Alington, his daughter in tail [sic].
In default of an heir he leaves the sum of ten pence 'per diem' to five poor men in honour of the five wounds of Jesus Christ, and to five poor women in honour of the five joys of the Blessed Virgin Mary; the said men and women being nominated by the Mayor and Recorder, and by the Master of the House or Hospital of St.Thomas de Acon, in manner prescribed.
