Lewis McDonald/Jane McKenzie

[Matriach]

Hello everyone

This is a general enquiry. I wonder if anyone is researching families that may overlap with mine as I am having problems sorting out my McKenzies.
Lewis McDonald married Jane McKenzie in December 1893 in Alness (why when they lived in Kildrummie, Nairn?)
Jane's parents are down as John McKenzie and Jane McKenzie (bap. 15/3/1845 in Delnies, Nairn?)
Jane had a sister Louisa born 1885
Lewis & Jane/Jean McDonald lived at 14 King Street, Nairn at least until 1942

I would  like to know who was John McKenzie and if anyone is aware of the children of Lewis and Jane McDonald esp. Ewan 1894 , William 1898, John 1900 and Louisa 1906.

Any suggestions appreciated.
