Hi Notfef, thanks for looking, I thought you might have had an index to make it easier, so don't spend too much time on it.
If you've spotted a possible family of hers, ie William, Sarah & kids, then let me know, because maybe Sarah junior was working away from home, which means she could be anywhere and came back in 1859 to marry in Bedford.
Thanks again for your time. Regards, TonyR.
