Hi. Thanks for your reply. John Simpson & Agnes Orr's daughter Jean was my line. She married a James McKenzie in 1833, Larbert and she died in 1882. Her and James are buried in Larbert. Their son Thomas came out to NZ and settled here.
Still looking for Jean's mother, Agnes Orr. Don't know a thing about her except she died between 1851-57.
Yes there was a Mary, born about 1824, She married a John Wilson.
Mary died in 1900 Avonbridge.
I have an Agnes, dau of John & Agnes born about 1823. She married a John McRuer, is this your line ?
John Wilson mentioned above was at McRuer's house in the 1881 census.
have quite a bit more info on McKenzie family just let me know.
Cheers
