LHRJ on Family Tree Circles

Hi,
Hoping someone can help me,my paternal great grandmother was recorded in documents as being born in Huntly,but in others in Aboyne.She died in 1920 in Fife and from her age given on death cert.would have been born around 1863/4.Can't seem to solidly find a definate birth for her as she used two different maiden names on documents throughout her life,which is very confusing for me,she went under Catherine Harper and sometimes McPherson as maiden names,looking for anyone who are researching these names in that area,and who could maybe help.

Thank you.
