The children of Richard & Margret would share exact same group of grandparents as Eliz jane, also she would be niece to both parties.
Richard took over this farm from his father, must have been pre 1859 as Eliz Jane was born Broadwood, this is where he was born and the family lived in 1841 - 1851 census
Next up on census is Carly farm with William Uglow (wid) and family, as mentioned there are a few sons which could possibly have fathered Eliz Jane
