Have you contacted Jennifer Mather? She is the genealogist of the Constance branch of the family as she is a great grandaughter of Constance and Walter Mather. I'm the great granddaughter of Hermance. Constance married twice, being widowed from Arthur Bentley (possibly a relative) with three small children. She and her sister Mayence went out to South Africa. Constance stayed, married Walter Mather, had eight more children, opened a boarding house and lived into her nineties. Mayence and her husband (maybe) W. S. Bent went north to Nairobi where they tried farming but Mayence ended up opening the Stanley hotel, which she ran with her second husband,Fred Tate, until Fred's health necessitated a return to England in 1937. She kept part ownership of the hotel until 1948, was the guest of honour at the opening of the New Stanley Hotel, and lived to her nineties too. She had one daughter, Gladys.
