Hello Barbara,
Yes I saw most of that,
Here is a census for the Rolley's. 1881. not sure if you have it.
Dalmellington Road, Drybridge, ( Hamlet )
Rolley William, Head, Ag. Lab. M. age 40 years, M. born Kirkoswald, Ayr,
Rolley Margaret, Wife, M. age 39 years, F. born Kilbirnie, Ayr
Rolley James, Son, Coal Miner, age 13 years, M. born Dundonald, Ayr,
Rolley Isabella, Daur, age 10 years, F. born Dreghorn, Ayr,
Rolley William, Son, age 8 years, M. born Dundonald, Ayr,
Rolley Margaret, Daur, age 6 years, F. born, Dundonald, Ayr,
Rolley Mary, Daur, age 4 years, F. born, Dundonald, Ayr,
Rolley Hellen, Daur, age 2 years, F. Born, Dundonald, Ayr,
Rolley Robert, Son, Age 1 month, M. born, Dundonald, Ayr.
On Scottish Census Records, do not take places of birth as certain.
Do you not have the actual marriage certificate of William Rolley, and Margaret Allan, 1866. which would give the parents names of William Rolley, and Margaret Allan.
Regards
Jonn.
