I note the marriage on freereg 26 July 1708, it looks likes their only daughter was baptised 5 August 1708. There are possible burials for Aaron & Sarah 14 Aug 1719 & 22 May 1725 respectively, sadly no ages.
Also a possible baptism for Sara ROABART 26 Feb 1687/88, Paul : St Pol de Leon : Parish Register, Father Thomas but nothing for Aaron, the record if there was one may not have survived. There is a John Victor in the parish around the same period.
Most of these records are also on this site under Cornwall Resources.
