A little more on the Clingan side...Guesses really unless we can find something definitive to firm up.
We had a possible 1841 census entry for a Grace Clingan aged 15. Andrew who showed as head, a brother maybe?
From 1851:
Andrew Clingan 41 Grocer And Innkeeper b. Kirkpat, kirkcud
Janet Clingan 29 housekeeper, sister b. Kirkpat, kirkcud
Andrew C Mcgeorge 8 nephew b. Kirkpat, kirkcud
James C Egan 2 nephew b. Kirkpat, kirkcud
Mary McKen 17 servant
Address: Main Street, Kirkpatrick Village
Wondered whether this could be a possible birth entry for Andrew for example here
https://familysearch.org/ark:/61903/1:1:XYMG-C94 Also, Janet sister
https://familysearch.org/ark:/61903/1:1:XY73-CLZ I think Andrew married later in life
https://familysearch.org/ark:/61903/1:1:XTR3-5FS and in 1861, Andrew with new wife and mother Janet:
Andrew Clingan 51 General Merchant
Mary Clingan 40 wife
Margaret J B Clingan 1 daughter
Janet Clingan 75 mother b. Kirkmahoe, Dumfrieshire
Margaret Whitenight 18 servant
James Gibson 37 lodger
Address: Temperance Hotel, Kirkpatrick Durham
