Hello,
Ancestry website shows several Coutts families living in the Durris area.
Someone has already mentioned 1841 Census. Janet Coutts, age 60, living at Lochton, Durris.
There is also a Jannet Coutts, age 40, living with her family at East Balbridie.
(Adult ages on the 1841 Census were rounded down so Janet could be aged anywhere between 60-64)
1851 Census, again as already mentioned, Janet Coutts, age 74, Stocking Knitter (pauper) born Glenmuick, Aberdeenshire. Appears to be living on her own at West Funich, Durris.
1861 Census, Janet Coutts, age 83, pauper, born Glenmuick, Aberdeenshire.
She is boarding with Isabella Thomson, age 66, pauper, born Birse, Aberdeenshire.
This is written in the space for the address:Todd's Glen Note sce Memorandum Boot.
(That might be a transcription error for: Note see Memorandum Book.) I have no idea what it means or if the same is written on the actual Census Return.
Might be worth contacting the main library in Aberdeen or The Aberdeen & North East Scotland Family History Society (ANESFHS) to see if they can help.
