I too am looking for Dalby's from York, though mine is a Robert Dalby, born according to the Census' in York, in 1800. he died 10 DEc 1881 aged 81. He married Mary Harrison 7 Nov 1828 and had 6 children: Elizabeth born 1829 George born 1834 Jane born 1837 Emma Born 1840 Sarah Born 1844 William Born 1848
I descend from George. I do not know of any parents for robert, though I do know that there appear to be no Robert Dalby's born in YORK ITSELF +/- 2 years of 1800. So I am stuck. Perhaps your Francis and my Robert are Brothers or Cousins??
I would appreciate it if you could give me some clues! THanks Brian
