I think I have the information on George Edward Dalby. He was born in Hunslet, Leeds, Yorkshire in 1890. Parents were Edward Thomas Dalby and Florence Louisa Wright. Father died in 1891. Mother remarried twice, first to Mr Johnson in 1893 and second to Edward Ackerman in 1898. Mother and her 3rd husband disappeared in 1901 (no record in 1901 Census). George Edward Dalby was a 11 year old boy residing at a boarding house in Norfolk in 1901 Census with his half sister aged 5 year old, named Grace Johnson. I have failed to find George Edward Dalby records (marriage & death) in England and Wales up to 2000. Maybe he emigrated abroad? Is he the right one you are seeking? He would be my 2nd cousin, once removed.
