Lesley was from his first marriage.
Sir Norman David Fenton Echlin, 10th (and last) Baronet of Clonagh, Kildare. Sadly it was a riches to rags story, with the fortune (and it seemed to have been considerable) being mostly lost due to a 20 year lawsuit at the beginning of the 1800s.
He was born 1 Dec 1925, and succeeded to the baronetcy (cr Ireland 1721) on the demise of his father, 1932; edcuated a the Masonic Boys' School, Clonskeagh, co Dublin; Capt (ret) Indian Army; m 1953, Mary Christine, only daughter of John Arthur, of Oswestry, Shropshire. No children. Heir: none.
Norman did well in the Army. He was we believe the longest serving Baronet in the UK, as he was only about 6 when he inherited the title. His family were staying at a house in rural N Ireland when the 9th Bart died and Gillian's father, then 16, was dispatched with a neighbour on a motorbike, to a nearby town to send a telegram about the news, but the bike was hit by a van and her dad was badly injured. I think Norman and his mother went to a relative of hers on the I of Wight.
One of the Ryde Inshore Rescue lifeboats is named Sir Norman Eclin Bart, as he was so active in fundraising for it.
