I think this may John McKinnon's entry, showing as stepson in 1891:
John Mc Kinnon
Born 4 Dec 1865
Birthplace ROTHES,MORAY,SCOTLAND
Parents Alexander Mc Kinnon and Margaret Riach
This couple also had a Janet (Jessie is common variant of this name) in 1854:
Janet Mckinnon
Christening 10 Nov 1854 ROTHES,MORAY,SCOTLAND
Birth Date 02 Nov 1854
Father's Name Alexander Mckinnon
Parents Alexander Mc Kinnon and Margaret Riach
I thought this might be Janet in 1881:
Janet MacKinnon, 26 General domestic servant at the Grant household at Ellachie Cottage, Aberlour, Banff
