Elizabeth OSBORN was baptised in March 1775, so she would have been approx. 73 at the time of her death.
Barleymow, I believe you have found what I'm looking for. St. Andrew's Church was where Elizabeth was baptised and married. I thought she may have been buried in Bourne, after ending her days there in the Union Workhouse.
Thanks to all those who have looked this up for me.
