being at a bit of a loose end for a mystery, have been poking around on this thread again.
I have done a few searched on the 1911 census...haven't found Kate Eade for sure anyway, there is one possibility. Which I'll put up in a minute.
But regarding the Kennedy O'Brien Martyn's...I found them on the 1911 census, and regret to say, no Kate Eade..also thogh, there are only two children at home, Kennedy O'Brien jnr aged 14 (he's the oldest boy) and Agnes who is 11, no sign of the younger son, Brian i think he was.
I then did a couple of other searches, playing around with doctor as occupation, Kennedy as first name - nothing, Obrien as a surname - nothing Kennedy as a last name, 4 results showed up, only 2 in London area: John Kennedy - Bermondsey and a David Given Kennedy - Hampstead.
Another search I did was Eade & occupation Nursemaid...that came up with a Nellie Eade, b.1888, living in Kingston, Surrey
Okay, on Kate/Katherine Eade
katherine Eade - servant - single 24 - b. London Hammersmith - working for Henry Arthur Dowsing living Fulham, London
kate Eade - Boarder - single - 22 - b. Whistable, Kent living at Epsom, Surrey
Kate Eade - servant - single 25 - b.Blackfriars London, working in Thakeham, Sussex (interestingly with a Mary Eade, aged 27, born same place)
So, at least these can be looked at and eliminated if required! (I know I'm mad...but I had these credits left, and didn't have anyone that I could look up of my own...and I only viewed the transcripts
)
