Robin P Cox, of Canada, says his grandfather is William Cox born 1873 died 1943, married Rose Catlin in Redbourn both buried at Redbourn. Was William also born in Redbourn?

The 1881 census CD shows that the following two families were living on Redbourn Common:

John COX	Head	48	Laborer	West Bradenham, Norfolk
Sarah COX	Wife	40	Hat Sewer	Redbourn
John COX	Son	20	Laborer	Redbourn
Susan COX	Daughter	17	Silk Weaver	Redbourn
Mary COX	Daughter	14	Silk Weaver	Redbourn
Leonard COX	Son	10	Scholar	Redbourn
James COX	Son	4	Scholar	Redbourn
William COX	Son	7	Scholar	Redbourn

 

Eliza CATLIN	Wife (Head)	36	Hat Sewer	Southend, [Redbourn]
Ellen CATLIN	Daughter	12	Scholar	Redbourn
George CATLIN	Son	8	Scholar	Redbourn
Rose CATLIN	Daughter	4	Scholar	Redbourn
Amy CATLIN	Daughter	2	Scholar	Redbourn

However Cox is a comparatively common surname and so you must be very careful not to jump to conclusions - and you would be advised to get at least the William Cox/Rose Catlin marriage certificate to check William's father's name. (You may also find it useful to read several of the pages accessed through How To ... while Right Name, Wrong Body? shows why you must be careful to check at every stage.)

If you can add to the information given above tell me.
