I have had contact with June Young before and apologise for the lack of info returned. My father is Prof Alexander Dalgarno, born London 5 January 1928, whose parents are from Aberdeen. He now lives in Cambridge, Massachussets and is Prof of Astronomy at Harvard. My mother still lives in Belfast and has now retired from teaching. My three siblings are Penny (married, two children, teaching in Ipswich, England), Rebecca (single, one child, behavioural psychiatric nursing in Nottingham) and Fergus (divorced and re-married, tow children, a solicitor in Newton Le Willows near Manchester). I would be grateful for a copy of any tree compiled to date.
