John 1721 and his wife Frances née Greenslade made their home and raised a family in Meshaw. He was buried there on 29 December 1763; Frances outlived him by 30 years and was buried in the parish on 13 November 1793. Their wills were proved in Barnstaple archdeaconry court on 3 February 1764 and 16 November 1793 respectively though the wills themselves are lost.11 Their first two children were baptized in the very small adjoining parish of Romansleigh, though this may have been no more than a convenience: children of several prosperous Romansleigh residents were baptized in Meshaw in this period. Their eldest son, John, was baptized on 3 December 1745 (John 1745), and a daughter Elizabeth was received into the church there on 4 March 1746/7, having been baptized privately some time previously. Baptism dates for several of their remaining children have not been found but their burial dates and other information taken from wills enable them to be identified with reasonable confidence. Thus James, born c1756 (James 1756), married Mary and although no other details have been found a common headstone in Meshaw churchyard records his death on 18 April 1818 aged 62, hers on 5 August 1824 aged 65. William, born c1757 (William 1757) died a bachelor in Meshaw on 13 February 1843, aged 87. There followed Richard, bap. 19 October 1760, bur. 6 February 1762; Mary bur. 19 June 1762; Joan bur. 19 June 1762; Richard bap. 7 March 1762, bur. 28 October 1770; and Roger bur. 1780. The long interval between the baptism of Elizabeth in March 1746/7 and the birth of James c1756 may be due to deficiencies in the Meshaw church register, which may also explain the missing details for the younger children
