Hi Jo,
2 places srping to mind, firstly, he could be buried in the churchyard of Bridlington Priory Church, where there are a lot of graves very closely packed together, but there are a lot of headstones in good condition.
secondly, there is a very, very large cemetery in Bridlington, I wandered around it a few years ago, but can't remember the name of the road it is on.
There may be other places he could be buried, I'm not overly familiar with the burial grounds in Brid.
sorry, I can't be of more help
Bee
