On twitter, an account that normally posts (lovely) photographs from silent-era Hollywood published a photo of an English Actress - Julia James.
It also stated that "little is known of her" beyond b1890 d1964, and on stage 1905-1920.
"little is known" is a challenge.
A delve into the BNA revealed that in 1921 she Married Maurice Dollfus, a wealthy banker from France. FreeBMD confirmed the marriage.
Another article reported that in 1909 she (and her mother) was robbed of £1,500 in jewelry, (£147,000 in current terms). More importantly, the article gave an address; 52, Bloomsbury St.
Optimistically, I used FindMyPast to do an address search, and got a hit! Since I don't have a current FindMyPast sub, I got the Census from Ances*y.
This listed a mother, a brother and a sister, as well as Julia Herself.
I can find no other UK records for any of the 4. I strongly suspect a name change.
Can anyone do better? To provide motivation, I attach her portrait, from 1912 (she was 20).
