Mary Ann Tennant was born in Glasgow c1846 and came to New Zealand c1864. She married a Byrne, was widowed, then married my great-grandfather James GUNSON. She had four sons and died when my grandfather, William GUNSON, the youngest boy, was ten. I cannot find where she was born in Glasgow.

Have all Tennant researchers read "Broken Blood. The Rise and Fall of the Tennant family" by Simon Blow? This is the story of the Tennant family and their chemical business in Scotland
