From the 1919 border entry:
Tarling, Violet, age 29 (definitely a 2, but the second number is hard to read), female, single, occupation - clerk (something below clerk is illegible), citizen of England, last permanent residence - London, England, nearest relative - 80 Pretoria Road, something like Layttonsfane, England, final destination - Malone, New York, going to join brother Albert, 6 Washington Ave., Malone, NY, planning to stay permanently, born King Langley, Herts., England
(I was typing at the same time as Anna.)
I can see Violet in the 1901 Census in Watford, Hertfordshire with her parents & 7 siblings, but no Albert.
In 1891, they're in the same town and Albert J.C. Tarling is there. He's age 8, a scholar, and born Hackney, London.
