Jessie Merle Lees

Jessie Merle Lees was the daughter of Leslie O S Lees and Jessie Clarence McCreery, born 1915, Sydney.
I can trace her living at Jess Cottage,73 Riverview Road Undercliffe nsw with Lees family members.
The last trace of Jessie Merle is at 8 Patrick Street Chatswood, nsw with her father, Leslie O S Lees, in 1949. This detail came from NSW Electoral rolls.
I can find no further mention of Jessie Merle Lees.
I would be delighted if anyone is able to help.
Morris Lees.
