Most of the information I have relating to Frederick William Montague Stone has come from another researcher who is descended from Frederick.
Frederick was the son of William Edward Stone and Caroline Martha Graham. He married twice, firstly to Kate Evelyn Stanhope Elliot and then after Kate's death to Linda Florence Hayes.
Frederick and his first wife, Kate, had at least 5 children and then he and his second wife, Linda, had one daughter.
Frederick's sons Arthur and Frederick both served in the 2nd Dorset Regiment in Madras. I found an Army Attestment record for Frederick which is of interest.
