Postcard names and people - Ruby or not Ruby?

[sheeponahill]

I am trying to decipher the names and identify the people in this postcard from 1905.
The names at the top appear to be: Ruby - Cousin - Lusa
That said, "Ruby" has a lot of superfluous lines and might be something entirely different.

The house is 2 Oakwood Avenue, Beckenham (now a block of flats). It was home at the time to Francis Alexander Barton (1861-1939) and family (wife Clara, daughter Mildred Gwendoline and sons Dudley and John). The card's recipient Mrs Evans in Lausanne was Jean Playfair Evans (1872–1956). Not a Ruby in sight...

Who is Cousin Lusa 

[sheeponahill]

Because of the dashes between the words, I’ve assumed that “Ruby”, “Cousin” and “Lusa” are different people. That said, it seems odd not to have named the cousin, they’ve been properly relegated to “some random relative” status.

There are 3 ladies in the photo but could it be just one is named ie the relative?

Surname - relationship - first name

"Ruby" is the surname, cousin the relationship and then the first name or even the name of the house?  Looks like it might start with an A. 

Was Mrs Evans a relative of the Barton family or don't we know 

Just an idea.

It's clear to me that the first word was corrected. There is, in my opinion, no way the first letter (with all the extra lines) represent a single capital letter.
But right now I don't see what was written first, and what was the corrected word.

It looks like an A to me too..

As a bit of context, the house was home to Francis Alexander Barton, a GP with a fascination for flight. He built and co-piloted an early airship in July 1905, four months before this postcard.

He can also claim Britain’s first airmail delivery, with a balloon flight across the Channel in 1902.

Maybe 3 surnames, but the ladies (middle and right) appear to be related if not sisters

Was there anyone in the family named Lesley, Leslie, etc.?
