This is my own branch of the family. There were Alsbury's living in Corston, Somerset, from c1738 to 1929.
The wills of some of the earlier family survive and there are quite a few references in parish records such as churchwardens accounts.
On an occasion in the early 1970's when I went there to look at parish registers, I met an elderly lady who had herself known the last of the Alsbury's to live in the village and, unprompted, used the same pronunciation as our branch do - as 'ALE-SBURY' rather than the other common pronunciation variants: 'ALL-SBURY' & 'AL-SBURY'.
In the mid-nineteenth century a good number of the family moved from there, and the nearby city of Bristol, to Derby through opportunities of work with the railway companies.
The gravestone of Francis Alsbury , who died in 1772, and is ancestor of all these, is still standing in Corston churchyard.
Corston, and the adjoining village of Newton St Loe, lie just to the west of Bath.
