I'm guessing that you have her line going back so I'll just tell you what little I found on her going forward:
born Aug 28 1859 in Skt Marie's parish, Frederiksborg to parents Anders Jensen and Juliette Caroline Olsen, she married August Julius Hammer who was born July 7 1855 in Sweden. By 1916 they were living in Kobenhavn. August Julius Hammer died sometime between 1921 and 1925.
...and I suspect it was in Oct 1921- but haven't been able to locate his death record.
Not much, but I hope it helps,
(and I'm sure that you already have this but... Anton Julius Jensen was born Aug 3 1856, also in Skt Marie's parish, and living in Melbourne at the time of his father's probate)
