Hi Janice. So a direct answer to your question:"I saw the name on here and wondered how many McPhail people were living in Hebburn at the time my dad was born"
The answer is: NONE.

Archibald & Ellen (born 1878) & son Archie, aged 1, (Your Dads' parents & brother) were living in Jarrow. Moot point, I know.

Search of the 1901 Census shows NO McPhail surnames in Hebburn. And just the 3 above named, but in Jarrow.
