Re: stock family from Bermondsey/Southwark

I am tracing Ellen Stock who married Zechariah Perryman in Southwark January 1849,They migrated to Adelaide in Australia later that year on the "Cheapside".

Her marriage record indicates one witness was John Stock, a farmer. She gave birth onboard in September to Elizabeth, and later had a second child who only lived 2 years (1852-1854). Zachary remarried in 1869, declaring that his former wife had died about 1854.

At this stage, I can find no record of Ellen snr's death, and nothing else about her life in England prior to her marriage.Could this Stock line be connected to yours?

Any prods or pointers gratefully received
