Hi! Wooddvillecaz
The records do give both Kenneth's and Jane's names and place of abode but not the former's place of birth, which is what we are after.
Kenneth continued to be a family name down through our branch of the Mclean family from Kenneth jnr (b 1792) and his son, George (b 1829).
The archivist at the Borthwick had some good ideas, I think, for other possible clues. I'll try and contact Teeside Archives sometime, but it might take me a while to find the time, I'm afraid.
All the best
Belem
