If you just say "Birth"...and the inline citation ref number, I actually have to follow the link to find the date.
Wouldn't it be better to say "Birth 1930" and inline citation ref number. That way you can follow the link if you want to, but if you don't, you do have the date.
Even better would be:
Birth 1930 in Leicester in England...??? with the inline reference?
I see you've put it at the beginning of the biography, but you can actually only put it once under "Birth", and remove it from the top.
