I have got back to Robert M Charles on the 1891 census in Rathen, E Aberdeenshire.
He is listed as 12 yrs old, birthplace Aberdeen.
Head of the house is James Sim (36? yrs) farm worker, wife Lizzie Sim 33 yrs, other Sim children are James 8 yrs, George 6 yrs John 4 yrs and William 1 yrs.( youngest 4 born in Rathen, eldest like Robert M Charles born in Aberdeen).
Robert Mutch Charles marries in 1900 in the district of St Nicholas, to Jeannie MacFarlane.
He says his father is Robert Charles - farm servant ( does not state desceased), gives his mother as Elizabeth Park, afterwards wife of James Sim - farm worker.
I cannot find a marriage of Lizzie/Elizabeth Park to Robert Charles nor a birth for Robert M Charles, nor Robert M Charles aged about 2 in the 1881 census, I searched Scotland, England and Wales, although I expect he is in Scotland.
I am new to research in Scotland, and although learning fast I am keeping my fingers crossed that some kind person will steer me to other records.......
Thank you
Lee
