Colonel Sir Andrew Marshall Horsbrugh-Porter, 3rd Bt

Years of birth and death from Wikipedia.

From this website http://www.turtlebunbury.com/history/history_family/hist_family_b_c..., authored by Irish historian Turtle Bunbury:

"Robert and Mary’s only daughter Annette Mary was born on 28th April 1908 and married in the Holy Trinity Church at Sloane Street, on 21st April 1933, to The Times polo correspondent Colonel Sir Andrew Marshall Horsbrugh-Porter, 3rd Bart, DSO and bar. The H-Ps lived at Chipping Norton, Oxon, and had issue."

From Wikipedia - that issue included Sir John Simon Horsbrugh-Porter, 4th Baronet (1938–2013), who was succeeded by Sir (Andrew) Alexander Marshall Horsbrugh-Porter (1971-) the 5th Baronet. And from the Daily Telegraph, 3 Oct 2006, we learn that the 5th Baronet's wife, Jennie Horsbrugh-Porter (nee Downing), gave birth on 25 September 2006 to a son, William John Ernest.
