We have the marriage of Frances Lewiston to Robert Pilbro and a somewhat messy 1911 census for them both.

http://search.ancestry.co.uk/cgi-bin/sse.dll?db=1911England&indiv=try&h=979478We feel this could be a false declaration by Robert, saying that his wife was living with him - as we believe the Frances Smith we found in the 1911 census with children Constance and Ellen is the same person.
Our thinking is that Henry, although married to Mary Ann Lewiston, at some point coupled up with her sister Frances - something we are trying to prove.
There is a possible death for Robert Pilbro in 1925, and a marriage for Frances Pilbro and Henry A Smith in 1926.
Awaiting certificates to confirm some of these facts.
There is no record of Henry Arthur Smith, his wife Mary Ann or sister/partner Frances going out to South Africa - or indeed any of them returning to UK - or at least none that we can find. Henry Arthur Smith and wife Mary Ann (Lewiston) seem to be back in the UK by 1907 when they were witnesses to the marriage of David Ignatius Smith (born as David Lewiston).
Trying to find either baptism or birth certificate for the two chldren, Constance and Edith, in order to find out their true parentage.
