A two part question.
The following text is copied and pasted from Hew Morrison's transcription of the Durness Parish Register.
MARRIAGE
1769 Neil MacLeod in Grudie married Janet nin Nishvicorish in Naultan 20 June
BAPTISM
1772 Neil Macleod in Saingo, Isobel 18 Jan
1775 Neil Macleod in Saingo, Janet 21 Feb
1777 Neil M'Leod, alias macnishmacen, tenent in Durin, Angus 20 July
1780 Neil MacLeod, alias macnish macEan, tenent in Durin, and his wife Jane Campbell, alias nin Nish, Alexander
Question 1: Are Janet nin Nishvicorish and Jane Campbell the same person? I mean, they are each "nin Nish" so it seems like solid ground, but I'm looking for confirmation that it is more likely true than unclear.
Question 2: What is the likely English rendering of Rev. Thomson's phonetic transliteration "nin Nishvicorish"
