Hi Bunny
Who's for quads? Ooh, our poor mother

Actually, I'm a bit worried about that link to Ipswich affecting the validity of my link to Bury St Edmunds so need to be careful.
At the moment my sole piece of evidence is a death notice in the Bury & Norwich Post 7 Jun 1826 saying
Cambridge, June 5th
Died
On Thursday, aged 55, Mr William Prigg, formerly a tailor of this place
It's that 'of this place' that I think is ambiguous, but I'm hoping a Bury St Edmunds newspaper would only be interested in tailors' deaths if there was actually a connection to Bury
There's a baptism at Bury St Edmunds, St Mary's for William Prigg
Baptism date 23 Apr 1772
Father Robert
Mother Martha
Notes 3y
which just about fits but is still inconclusive, but so far, my best shot
The search continues...
