Hi Belinda
Maybe we can exchange information.
I have also been researching for the family of Richard Henry Smith and Nellie Maud Samways.
My wife is a granddaughter of Richard Henry Smith but from his first marriage to Edith Ellen Middlemiss.
I only knew of 2 female children from Richard Henry Smith and Nellie form his death certificate now I have the names one was born about 1935 and the other 1936.
I have info as Nellie Maud Samways born 21 Feb 1904 died 29 August 1972 in Blenheim but that's all, I don't have the certificate.
Richard Henry born 2 Nov 1893 in Greytown married Nellie 1933 and he died 22 April 1964.
Interested in hearing from you.
Paul
