I have just checked the GRO records for the son of latter Margaret Grieveson mentioned earlier in the post.
His name appears to have been Henry John Grieveson if he is the one who was born in Gateshead in 1854. Mother's maiden name is given as Dodds.
I believe Edward Senior's wife's Mother was called Mary Dodds before she married William Innis.
So there could be something in Margaret Grieveson having been a relation on the female side.
