I have two distressed books/directories, not sure of the date of the or the title as the first pages are missing

but I have found some information on John Elsam
In the one I think is dated about 1840
he was a Councilor
till Nov 1843also listed under
WHITESMITHS [AND NAIL MAKER] High St Boston.
The later book has the Town Council [1855-6] where he is an Alderman and also a Borough Magistrate.
Now Listed under Ironmongers, Bridge foot. High St
Hope this is of some interest to you.
