Having found Elizabeth Ann Clayton again (one of the Clayton sisters mysteries), I now have to look for Marian Martha/Edith Marion Clayton after her marriage to Claude Gibson in 1881. I have been trying to find her for many years, without success.
On another note, I am also looking for actual marriage certificate for their son, Francis Charles Gibson who lived in Accrington and married in Lancashire in 1899, to a Mary Elizabeth (also Elizabeth Mary) Fielding or Hindle (I suspect mother not married but John Hindle, Engineer is on the marriage certificate as her father). I have seen this marriage certificate many years ago on the internet but I can't find it now, anywhere. On it Francis (Frank) states that his father is Claudius Gibson, formerly in the military in South Africa, deceased. Claude was not deceased but fighting in the Boer War at the time of his son's marriage. Claude was taken prisoner in 1900 and sent to a camp in Ceylon.
