Ancestry UK I believe is a pay site, but I think I'm at an end without it.
Haig had one son, Rollo Amyatt Wolseley de Haga Haig and two daughters. Rollo was a gifted pilot and joined the RFC in 1916 (having previously been a Captain a Territorial Field Artillery regiment). He served throughout WW1 and became a noted test pilot (he was the only man ever to put a Vimy bomber through a loop-the-loop manouevre!). Tragically Rollo was drowned in 1936 while yachting. He left a daughter and also had a sister.
Some stuff I found atached which may be of interest.
