Yes thanks, I should have said, I followed that Daniel Bird b. Ampthill through the census, and he's in the 1881 Luton at the same time as 'my' Daniel is in Huddersfield
And yes, Francis Zipfel is a little mystery all on his own, born Norwich c.1828, think I've got him in East Dereham Norfolk in 1841 aged 10 staying in an inn, then nothing til he turns up in Huddersfield in 1871 as a hawker, his family were all clockmakers so I don't know why he's gone awol except that his mother died in 1838. And yes, the name is open to very many mistranscriptions, Tipple, Lipfel, you name it.... this last query has come about because I amended
Griffiths to Zipfell on ancestry's 1881 index and a family member has got in touch with me through ancestry to find out more about about Mary & Daniel
Oh thanks very much John, that's a brilliant variation to add to my list, (Clockhill) -- well done for the death reg and the 1891, you're a star!
