I have a birth certificate of my grandfather who was born in Ecclesall Bierlow in 1892. It gives EB as being in the Counties of Sheffield and
York. I note that the pre-printed part of BMD certificates has "Count__" allowing for a "y" or "ies" to be added. However, Sheffield isn't and wasn't a county, and a place can't be in more than one county anyway, can it?
Can anyone explain what it means?
