thanks Ian. My information about Thomas Pounder and Ann Harrison was sketchy and at least partly reliant on a very worn gravestone in the sandbanks cemetry in Hartlepool. You've left me wanting to check a couple of things. I'm sure we have the connection right. Two of their great grandchildren were called Eden Pounder, both died in infancy.
I don't have anymore direct Harrison info on my tree but I do have a copy of a book that lists a lot of harrisons. This is 'The history of the Tees Pilots'. If you don't have access to this I can pass the info on. It also includes lots of Pounders.
I will mail to your friend in Australia.
I can tell you that the Harrison descendents - though not called Harrison are also in Spain and Zimbabwe as well as throughout the Uk.
If you want more on this a direct email to me - firstname.lastname@example.org might be appropriate
