Tacking on to an old thread, do those diaries have an online presence at all, would you know?
If not, would you happen to know whether they'd be likely to have any entries referring to Thomas King and/or family , mealman d1807, who I believe from the 1815 census might have been based at West Mills.
Nothing online as far as I know.
Extensive extracts from the Purdue diary were printed in the Newbury Weekly News in 1886 - which is what I have, not the complete diary. I makes for fascinating reading, but it is not a day to day account and includes lots about events distant from Newbury. There are occasional mentions of Newbury folk, but no Thomas King. It covers the period 1766-1803.
The Toomer Journal relates to events during his years as Mayor of Newbury (1791/2, 1801/2 and 1814/5) - lots of Newbury names mainly in lists (signatories of a petition, invitees to the Mayor's feast, publicans, charity school boys, almost random). There is a Thomas King - landlord of The Globe - and a John King, mealman but no Thomas King, mealman.
It's pure chance that they both mention the same event - Toomer sitting as magistrate on a case involving Purdue's brother in 1801.
