Anne Hayhow - Bedford 1808
In case it helps pin down the elusive Anne Hayhow (my gt gt gt grandmother), it should be noted that Joseph Asprey was baptised 6 May 1784 at Ampthill Beds, and was already a widower when he married Anne Hayhow at Bedford in 1808.
I think it unlikely, though not impossible, that she was any of the Ann Hayhows (or similar) noted in the IGI as born in Suffolk or Cambridgeshire in the 1760s, mainly on grounds of age. It should also be noted that there is not one reference in the IGI to any Hayhows living in Bedfordshire. It is of course possible that she was herself also widowed and therefore not a Hayhow by birth.
I am cross-posting this also from the Hayhow GenForum.
