You say there were about 12 Mathieson boys at that time. Do you happen to have a Charles? I am looking for a Charles Mathieson my Paternal Grand -Father married to a Maggie Jane McCrae. Not having much luck locating them. They both died in Aberdeenshire. Charles at Broadlands Cottage,Cairnie died on 12 March 1924.He was 51yrs old at time. Hope someone can shed some light on this family.
