Jan said to tell you Annies baptism date is 25 February 1866 not 1864 as she had in her email.
We have worked out that you and Jan must be second cousins - is that what you think? She has your annie marrying Wilfred Ernest Halifax - is that right? Her John Atkinson born 1871 married Elizabeth Key and they had Jan's mother, so the child that your Annie and Wilfred had, either mother or father, would have been cousin to Jan's mother, hence you and Jan being second cousins. Does that make sense??
