Thanks to you all. i have been looking through the links you have all sent, Just to follow up on the info I already have.
I have the 1911 census for Emily, and is in Devonport with her children Alice and Charles.
I have her husband Charles in the 1901 and 1911 censuses on board navy Vessels.
Her sister Nora is also in Devonport in the 1911 census, she had married a Francis Nichols in 1910 and he was actually also in the navy also shown on 1901 and 1911 censuses, in fact he was on the same vessel as charles in 1901, so it could be that Charles Introduced Francis to his wife,s sister, but we will never know that fact.
The wierd thing is that on the 1911 census Nora has her place of birth as Town, Northampton ?
on the 1911 census for Emily she does show her birthplace as Hull, which does make sense as her husband Charles was born in Driffield only 20 miles away.
