This is a little bit about Isaac Myers b1850, the eldest son of Maurice Myers and Elizabeth Abrahams, both the cousin and second cousin of Charles Moss Myers.
Following his father in the tobacco trade in 1881 he is listed as an Importer of Tobacco and in 1901 as Retired Cigar Merchant. It may have been through this work that he met his wife, a French lady Amelie Anne George, whom he married in Paris in 1887.
After his father's death, the family had moved to London and that's where Isaac died in 1909. His wife outlived him by nearly 50 years, dying in 1947.
They had 4 children. Their only son, George Maurice Myers, was a Private in the London Regiment and died in France 15 Sep 1915.
Their youngest daughter, Edith, married a man in Kimberley, South Africa in 1920 but returned to London later the same year without her husband. A son was the following year, who I assume was her husband's.
Their middle daughter, Julie, followed what seems to be a family trait and never married.
I'm not sure what happened to the eldest daughter, Eliza, but with a connections to France and South Africa she may have an interesting story as well.
Apologies Chris if this is already known
