Hi all and thanks for all the hard yards put in - I'm a bit overwhelmed but to take one point first, in the 1851 Census attached it shows Thomas as 'Un', not as assumed, 'Son'. Thanks Heywood, well spotted! Strangely, in the 1860 Census Thomas, still a Tailor has named his Son Blakey Hartley Abbott which implies there was some sort of affection shown here by Thomas for his former companions in the 1851?
That will help to answer your last (today) email, there was a deep bond of some sort?
