This is a previous thread about Henry Raeburn Brown.
https://www.rootschat.com/forum/index.php?topic=319429.0My reasoning about his parentage is a bit tortuous, but I'll try to explain.
From the 1841 census at Church Lane, Edinburgh St Stephen's 1841/685/1/143/12
Henry Brown 30 Tailor Midlothian
Janet Brown 70 Scotland not Midlothian
Ann Willson 35 Midlothian
Janet Willson 14 Midlothian
Agnes Willson 12 Scotland not Midlothian
George Willson 10 Scotland not Midlothian
Ann Wilson was the daughter of James Brown, gamekeeper. She married George Wilson:
1826, 23rd January. George Wilson, Blacksmith, residing in No 3 Dean Street, Stockbridge and Ann Brown, residing in Allan Street, Stockbridge, both in this parish, daughter of James Brown, Gamekeeper there, have been three times proclaimed in order to marriage in the parish church of St Cuthbert's, and no objections have been offered. Married on the twenty-seventh current by the Reverend Dr David Dickson one of the ministers of this parish. [Edinburgh St Cuthbert's Parish Register]George Wilson and Ann Brown had Janet, born 7 November 1826 in Edinburgh St Cuthbert's, and George, baptised 10 April 1831 in Dysart, Fife.
I haven't found a baptism for Ann Brown, but there is a baptism of Robert Brown:
1808. Born March 7. James Brown Grange Gardens and Janet Richardson his spouse A Son Robert, Baptised April 19. Witnesses Family. [Register of Baptisms James Place Edinburgh]Henry Raeburn Brown married in 1843:
2d January 1843. Henry Raeburn Brown Tailor residing in no 10 Church Street Stockbridge and Helen Clyde residing in same place both in this parish, daughter of James Clyde coachman residing in Rose Street have been three several times duly and regularly proclaimed in order to marriage in the parish church of St Cuthberts and no objections offered. Married this day by the Reverend John Bruce, one of the Ministers of the parish of St Andrews Edinburgh. [Edinburgh St Cuthberts Register of Marriages]Henry's children were James, William Slater, Helen, Janet Richardson, Henry and John.
So putting it all together it seems to me likely that James Brown, gamekeeper, and Janet Richardson must have been the parents of Henry Raeburn Brown, tailor; Ann Brown or Wilson; and Robert Brown. However Henry died before the start of civil registration and I have not found the deaths of either Ann or Robert.
