Thank you both for your responses Annie and Rosie.
Both ideas for the words down the side seem plausible. I'm unsure which is right yet!
Kilmallie is an interesting suggestion. There's a place called that in Fort William, but the closest I can see to that in Inverness is Kinmylies. I'll keep an open mind on that for now.
I'll try contacting Scotland's People too.
The address they all lived at in 1871 was a small croft 14 Kinkell District, Urquhart&LW, Ross and Cromarty.
Jane appears to have been born in the Parish of Inverness, Inverness-shire. So those places are unconnected. She also had a younger sister Anne born in Inverness in 1867. I will check her birth record soon to see if it gives any clues.
1871 Census...
Alexander MACDONALD Head 40 Urquhart, County of Ross
Jane MACDONALD Wife 29 County of Inverness
Jane MACDONALD Daughter 6 County of Inverness
Anne MACDONALD Daughter 4 County of Inverness
Regarding Jane Snr's parents... According to young Jane's birth record, Alexander and Jane Snr got married on 31 Dec 1863 in Inverness. I found an Alexander and 'Jean' McDonald who got married on that date in Inverness. If it's them, then Alexander has a different mother from who I previously believed. It's making me sceptical, and I'm a bit tentative to start following Jean's family in case she's not Jane Snr. The usual residence on that marriage certificate for both of them is Clachnaharry in Inverness.
What's making it even more of a challenge is I am struggling to find deaths of any of those 3 ancestors I mentioned. I can say with certainty they were all still living in 1911 though.
Jane married a Walter Chisholm in Inverness, a number of years after giving birth to my illegitimate g-grandfather Alexander MacDonald. Old Alexander and Jane Snr raised young Alexander on the croft in Newton Kinkell, U&LW, and were still living together there in the 1911 Census. He married a Jamesina Cameron in 1920, and apparently his mother Jane was deceased by then.
Establishing Jane's birthplace in Inverness, and matching it to her mother Jane Snr's family home, could go a long way to confirming where both these paternal and maternal MacDonald's originated.
Apologies for the long reply! Seems to help make sense of it all by writing it out.
Thanks again!
