SIR - My father Albert Rockall has been desperately trying to trace his long lost half sister for over 30 years.

Having tried and failed in the days before computers and the internet, he has recently handed over the task to my sister and me.

On his death bed my grandfather Albert Giles Rockall told my father that he had been married to a lady called Mary Goodman before he married my grandmother. However, in 1926, shortly after giving birth in Islington to a daughter called Dorothy Rockall, Mary had died tragically.

Heartbroken, my grandfather left England for Canada entrusting Dorothy to the long term care of a maternal aunt. Years later he returned to England and remarried fathering two sons (my father and my uncle) who grew up never knowing their half sister Dorothy.

We believe that my grandfather and his daughter Dorothy were never reunited.

In recent months my sister and I have uncovered some information relating to Dorothy Rockall. It appears from the births, marriages and deaths records that she married William Walstead Morgan in 1946 and around that time moved from Islington to Hatfield.

If our information is correct she had a daughter Carol in 1946 and another named Susan in 1951 and Susan may have gone on to marry Ian Gallagher in Hatfield in 1987.

Dorothy's husband William Morgan died in 1989 aged 66 in Hatfield and from there our trail runs out.

We cannot find any addresses in the Welwyn and Hatfield area for either Dorothy Morgan (who at 82 may be living in a nursing home) or her daughters Carol and Susan and examination of the births, marriages and deaths records has produced nothing more.

My father Albert Rockall is in his late 70s and it is now his express wish that we honour his pledge to his father to find his half sister or any member of her family.

Therefore, if anyone reading this letter can offer us any information that will help reunite a family we would all be both grateful and extremely delighted.

If anyone has any information they can contact my sister Penny on 07759 608026 or contact the WHT by letter or phone and the editor has said he will pass the details on.

Melanie Hickey and Penny Parisi,
