Many thanks Nell,
Apologies, my mistake, I meant Elizabeth and John Budden in the 1841 census. The marriage says "William Budden and Elizabeth Breadstry of Kempshot" (a transcription, I have not seen the original). Kempshott is part of Basingstoke, so perhaps that just means they were both living there and not necessarily born there.
I cannot find a record of Elizabeth Breadstry's birth in either Blacksall, Suffolk or in Kempshott, Hants, although I imagine Breadstry (if that was her maiden name and not a transcription error) was a rare name. I also cannot find her in the 1861 census, although she died at the same address, Church Lane, Basingstoke, given in her 1841 and 1851 census returns.
Thanks for the birthplaces of Betsy and Charles.
