In my database (3,000+ records) of Roff births, marriages & deaths extracted from UK Public Record Office indexes for period 1837-1899), I have a John Leneve Roff who married in 1853 in Islington (a borough in London). Also I have Elizabeth Isabella Leneve Roff who married in 1853 in Hackney (a borough adjacent to Islington in London). These are probably the 2 individuals to whom you refer. I have similar detail on several other 'Leneve' Roffs but no proven relationships - this is not a branch of the Roff's that I have any direct linkage to as far as I'm aware, but if you have any info that might show otherwise I'd be very interested.By the way, I am a UK Roff directly descended from Charles Roff of Chipping Norton(see my separately posted msg in this forum). Hope this helps!
