Hi Heywood,
Thanks for looking for Hannah. It is a bit of a mystery where she went to. We have discovered her date of birth: October 1855 (in the Whitehaven area). We still don't know Jonathan's date of birth. It was mentioned, earlier, that he could have been born in 1851, but with the census information that you found he was already born and three years of age, so it can't be that. I wonder if Seathwaite and Whitehaven are under different areas (not sure if Dettori28 mentioned this before). I will certainly send off for the marriage and death certificates and hopefully we will find Jonathan's date of birth and his mother's maiden name at some point.
Thanks also for the offer of helping us with further research. I will certainly take you up on that at some point. Thanks for the time and effort that you have put in to doing this research today. I think you have all been wonderful...
Best wishes to you,
Michael
