I've found five newspaper mentions on PapersPast relating to the elopement of Mrs Robinson and William Wakefield in Dec 1882.
The eloped couple are supposed to have had a child together - George William Wakefield, b. appr. 1884. I'm hunting for evidence of his birth, and I'd love to know what became of Mrs Robinson.
The couple ran away together from Fielding to Nelson.
I can't find a birth record for the child on BDM under either surname.
His father married someone else in 1885, and the son's marriage printout lists that wife as his mother.
I believe he was brought up by his father and the new wife - he appears on school rolls in Foxton with two younger sisters.
I believe Mrs Robinson to be Ellen Winifred GREEKS, b. appr. 1863, who I believe is the Helen GREEKS who married Richard Robinson in 1878.
They seem to have had three children:
1879 - William George Robinson, to Helen Winifred and Richard Robinson
1881 - Mary Anne Louisa Robinson, to Ellen Winifred and Richard Robinson
1882 - Ernest Robinson, to Ellen and Richard Robinson.
One of the newspaper reports says there were only two children. Another report says she took one child with her and left the other with Mr Robinson.
I'd be delighted with any further information that anybody can find!
