I found her in The Hague, born 1 oct. 1896 Greenwich
She came from London in The Hague on 24 June 1902, living with her Uncle Bauffe (=Bauve)
maybe you already know this, but to be sure I send it still
She for sure lived in The Hague untill 1939, the Registrations Cards of People go till 1939, after that I can not trace her online, if she stayed in The Hague or moved.
After the death of her uncle she stayed till 1939 in The Hague in home of her aunt,
maybe she moved with her aunt to Rijswijk.

I just saw that in 1941 Ellen Dorothy got her Pas (Pasport)
