Well I think that confirms the Bale/Ball issue. Confirmation of the baptisms of Mary and Ann together with the removal order from the National Archives which lists them as Bale means I definitely have the right family, now all I have to do is find tha elusive thomas!!.
Most of the children seem to have gone with them to Eaton Socon, as I have marriage and burial records for them there. The son Thomas must have ended up back in Wellingborough, as that is where he is convicted. I will go and check the census lists for Elizabeth,as I have another possibility for her as an Elizabeth Bale married in Wellingborough in 1818 and from census records she was born there too (which my Elizabeth was).
I also found a death for a Thomas Ball in Eaton Socon in 1824, but there is also one for Denford in 1833. Not sure what to do about that. From the ages they could both be possibilities, but the Denford one is more likely?!?!?
Census not much help. Elizabeth died 1843 in Islip/Thrapston so still not sure where she was born.
