Hi Jean,
But Jessie was female in both censuses!
The Queensland govt death index has:
Year/Reg#/First name(s)/Last name/Father/Mother
1933/ C2462/ Thomas Lennox/ Seaton/ Duncan Albert/ Margaret Duglass.
Hopefully ordering available certs would have been done. But we all know how many death certs are guesswork because memories about another person's life are faulty.
