Hi Brian
Perhaps we need to have clarification of what you do have and what you need:
I have found various sources for this family - do you have all this?
1) Father was Edward Robert (Roland?) MARGARSON - deceased before 1841
2) Mother Susannah died 1850 Wandsworth Surrey. She was born abt 1786
3) Susannah 55 and Emily 18 are on the 1841 Census in Clapham
4) Edward & Susannah also had a son James b abt 1808 who also went to Australia 1834 as a convict. Also a Baker.
5) Benjamin is on the 1851 Census?? as a Baker (but can't see him 1841?)
6) Emily married Samuel John CLOSE in 1845, had a number of children, died 1899 Hampshire.

On the First Families database: that same source X supplies information that Benjamin (b 1830) also went to Australia in 1834? Can't be right?
