Geo. Ferdinando 1862 in Bethnal Green

I am researching the Gresham line in London and have come across George Ferdinando as a witness at the wedding of George Gresham to Elizabeth Lepley, May 1, 1862, at St. James the Less, Bethnal Green.
The other witness was a Rosetta Gresham, who I am taking to be George's mother. Ido not have her maiden name and had been figuring she was a Ferdinando previously.Any Rosetta's in that line??
WEll, if not- its got to be your George anyway at the wedding of my great great great grand uncle!!
