if this is the burial of Eliza Saviel, it gives a year of birth of 1823
https://www.familysearch.org/ark:/61903/1:1:FGGT-DP6I'd wondered if the marriage could have been the widowed mother, but Elizabeth Frances Colliards was buried 5 Jan 1839 in the Howra Burial Ground, Fort William, Bengal aged 34 years 2 months 12 days, wife of T S Colliards Overseer of H C Salt Golahs, Sulkea.
Age in years doesn't fit with date of birth on baptism given as 25 Oct 1807
John Thomas Spencer Colliards was buried 24 April 1838 in Howra, aged 9 Years 16 days, son of T S Colliards
Thomas Spencer Colliard buried at Howrah 19 Aug 1850 aged 19 years 1 month 23 days, son of the late Mr Thomas Colliard.
Thomas Spencer Colliard died in 1841 without making a will, there is an administration & inventory. Likewise no will for his son.
There is a marriage in Madras 1833 for James Henry Saville & Sophia Deverano
