Jessie Cameron was my Great Grandmother.
She had Hugh Albert Charles Cameron 19 Aug 1905 to an unknown father.
She then married James Bagnall in 1908 in Wellington.
They had Florence M Bagnell born 1911 in Wellington. BDM has Bagnell not Bagnall.
Thelma L Cameron came along in 1912 to an unknown father.
Hugh understood that Jessie and James were divorced.
I hope this helps.
