Alfred Jacob, is the son of George Ferdinando and Elizabeth Lovell as is James.They had a Sister Elizabeth born 1st April 1815 and christened 21st May 1815 at Saint Matthew Bethnal Green.I wasn't sure whether it was her that married Henry in 1832.I certainly do not have any record of this.It would seem the most probable match as both Rachel and Eliza married members of the same family.Do you have any age information on Elizabeth at all from the marriage certificate?
I do have other Elizabeth's of that time in and around Bethnal Green.
Rachel went on to marry again after Alfred Jacob died but I don't have any information when he died apart from she married Thomas Rozee in 1865.She also had two Daughters, Rachel and Elizabeth.
If we can prove Elizabeth, it would be something having three Yetton/Ferdinando marriages between two families.
