There is no record of how Epstein met Meum, the slender, fair-haired woman, both seductive and demure, who became the mother of his first child. Dorothy Lindsell-Stewart (Meum was her pet name), the estranged wife of an army captain, and Epstein fell in love. The newspapers described Meum as "Epstein's favourite model" and she was soon a part of the Epstein household. In 1918, Peggy Jean was born. Both Margaret and Epstein were there, and Meum was content to allow them to bring up her child.
A W J Lindsell-Stewart was later discharged from the 7th KOYLI after he received wounds in 1916 & 1917.
