Full Abstract :
Administration of the estate of James
Brewster late of Dunseverick County Antrim Fisherman who died 26 July 1897 granted at Belfast to Mary Brewster of Dunseverick Spinster the Daughter.

1901 census has him aged 88 - Date of Birth of 1813.    Found his death in the Deaths Index at Derry Family History Centre.  He was given as Robert Brewster, aged 93, Coleraine, 1.368, 2nd Quarter of 1904.  This changes his Date of Birth to 1811.   

Probably buried in Ballylintagh graveyard under stone inscribed, "To the memory of the Brewster Family of Dromore".   (See explanation of church membership under Mary Brewster.) 

Found his death in the Deaths Index at Derry Family History Centre.  He was given as Robert Brewster, aged 93, Coleraine, 1.368, 2nd Quarter of 1904.  This changes his Date of Birth to 1811.  The death entry, from Dublin General Registry Office, shows: 5th May 1904 Dromore, Robert Brewster,  widower, 93 years, labourer, debility and old age uncertified, Mary Brewster, granddaughter, Dromore, Present at Death. 

A death notice in the Coleraine Chronicle on 7th May 1904 also gave his age as 93 (no other details other than that he was from Dromore). 

Dob from age 45 yrs in 1860 Philadelphia Census.
