For Littleton Ernest Groom (1867–1936)
P31 = Q5 (human); P569 = +1867-04-22T00:00:00Z; P570 = +1936-11-06T00:00:00Z; P19 = Q478302 (Toowoomba); P20 = Q3114 (Canberra); P22 = Q8012014 (William Henry Groom)
Claim values transcribed from https://www.wikidata.org/wiki/Special:EntityData/Q1865883.json. P31=Q5 and the birth/death dates agree with the tree, so the qid is safe to set; P22 corroborates the father.
