I am descended from a Jane Rooke born 1829 London and who married, 6 October 1845 St Pancras London,George Thomas Arkey born 1822 Leicestershire.
On their marriage certificate Jane's father is listed as Thomas Rooke, deceased Irish Traveller (gypsy) and there are no mother's details, as usual for this period!.
Jane's ancestry is therefore difficult to establish, however, when I saw your posting including a Lavinia Jane Rooke born 1829 London I thought I'd take a chance and write to you.
As she was only 15/16 when she married, and therefore a minor, perhaps her first name 'Lavinia' and her father's details were incorrect on her marriage certificate?She and husband George emigrated to Australia in 1853 on the 'Rattler'.
If you can possibly see any connection it'd be great to hear from you.I am in NSW Australia.
