First child. Moore family tradition says he died young, unmarried and childless in 1849.
However a sworn affidavit from Harriet Francis Pursey dated 29 August 1849 states that her son William Charles Pursey died on 1 May 1832 at Henrietta Street, Covent Garden. The affidavit further states that William was a bachelor and was buried at Covent Garden Churchyard on 6 May 1832.
Burial records for London (on www.ancestry.com.au) show no records of any Pursey being buried in 1832 - however they do show a burial record for a William Pursey on 24 May 1829 at St. Marylebone, Westminster, Middlesex (ie. London). He was recorded as living at Castle Street, age 25, born about 1804. This may be Richard Pursey's son, "our William".
