Someone posted a message on Ancestry boards looking for the death of Christopher Southern and Ellen Fisher Southern. She appears to be the daughter of Elisha Fisher and Elizabeth Boyd and somebody posted the death of Elisha from cemetery records :
Name of deceased Elisha Fisher

Age 62 Years
Date of death 9 July 1948
Date of burial 12 July 1948
Cemetery Dundonald Cemetery
Grave section and number C5 603
Burial type Earth Burial
Giving his birth c. 1886.
It looks like Elisha and Elizabeth went to Scotland after their marriage and Ellen was born there in 1907. They were back in Belfast c. 1910/1911 where their son Samuel Arthur was born. Their daughter Anne Boyd Fisher (Annabella?) was born in 1918 in Belfast.
You can find them on the 1911 census living in 30 Edith Street (Pottinger), Down) on this website : In order to find them put 'Elesha' down as the surname and 'Fisher' as the Christian name.
http://www.census.nationalarchives.ie/pages/1911/Down/Pottinger__part_of_/Edith_Street/220949/Elizabeth's father Samuel and her brother William James are living with them as 'boarders'.
Living next door in 29 Edith Street is a Mary Fisher who may be Elisha's mother.
