This is quite an old thread so I wonder, kd, whether you have obtained further information since last you posted
on the thread (25 Aug 2007)?
If not, I'd just say a few things:
1. I'd stick to my earlier interpretation slightly refined.
As follows:
Certificate of Baptism inside
{f}or a man of the name of Mobberl(e)y
{bo}rn at Royston
2. In the 1841 census (in Worcestershire), William's entry has "Yes" i.e. born in the County.
Of course that might well be a mistake.
Incidentally, I believe that the entry for Eleanor was initially 'F' (foreign) but that it has been overwritten
with 'I' (Ireland).
3. In the 1851 census, William's entry has his birthplace as "Ryston" (sic) without any County being specified
(and I think it says 'Nr Blind' in the final column).
4. In the 1861 census, William's entry has his birthplace as "Middlesex Riston" (sic).
