Thanks Donna , all is not lost . Isabel Taylor/Clucas Will said she was from Billiown , now you have given me Billiowin as the residence at the time of the deaths of Isabel 1758 , Henry 1752 and Henry 1782. Not much really HOWEVER William the son of "our" Henry was at Billown in 1841 on his own , and returned there with his family for the 1871 and 1881 census. So this is making Henry born 1779 as the most likely , his age at death of 62 in 1841 has always pointed to him.

Just a point if anyone can help , I now have three spellings Billiown, Billiowin and Billown , which of the three is correct

Thanks again
David
