On 16 February 1755 he had married his second cousin Anna Bosanquet, the daughter of Samuel Bosanquet.[2][5] Their first son, also Peter, was born on 19 January 1756, their daughter Jane on 24 February 1757, and their son Samuel Robert on 27 February 1759.[6] The eldest son, Peter, was buried in the North choir of St Helen's Church, Bishopsgate on 3 November 1781.[7] Peter himself died on 20 November 1788 and was buried in the chancel of the same church on 28 November.[8][9] A funerary monument depicts a woman, probably Charity, holding a medallion portrait of Peter Gaussen, and with three children below.[10][11]
Their third-born son, Samuel Robert Gaussen (1759–1812) was MP for Warwick (1796–1802)[3] and a collector of the works of prominent landscape painter Paul Sandby.[12] Peter bought Brookmans Manor in Hertfordshire as a gift for Samuel in 1786.[1]
