Great find Monica, I'm not sure how I missed that death for James Brown
The fact that Isabella left her mark when registering his death, adds something to the name/identity swap idea because, as we know, Jeanie was also unable to sign her name.
I don't know why James' name isn't on the 1925 VR for the Palmerston Place address but I've checked the VR's back to 1920, when a Mrs Elizabeth Kirkwood is the Proprietor - all the residents were female, same for 1925. I was a bit concerned at first but then I found this on the internet:
"Sims and Clare say that Ethel’s longest-lasting address in Edinburgh was 37 Palmerston Place. I did a day’s dredge myself in the Edinburgh Room at the City Library, through the Street Directories, the Valuation Rolls and the Voters’ Rolls. Referred to from 1926 onwards as Palmerston House, a legend still engraved on the glass above its chaste and dignified door, it appears to have been arooming house from 1920 onwards (though Palmerston Place, built from 1880 to 1883, had always been and still is a prestigious address, the last place you would expect to find such an establishment), with fifteen voters plus Ethel listed in 1926, though the average was usually about nine. They were accommodated on the three floors of this spacious house plus the attics. (The basement was occupied by one Mary Hinnigan, the caretaker, and was not a rated part of the house.) The rooms were separately rated, and graded according to their architectural status in the house. Ethel and Edith had the more modest rooms.
In 1921-2 Ethel lists herself as ‘authoress’; Edith is listed but indicates nothing of her profession, though in the 1922-3 Valuation Roll she describes herself as ‘a lecturer’. In 1923-4 Ethel is listed but Edith is not. In 1924-5 Ethel is still there, an authoress. The occupations of other tenants are variously given as nurse, shopwoman, clerk, cashier, missionary and masseuse, a respectable bunch of women going about their lawful business, but definitely girls of slender means, rather an unusual class of person to be living in Palmerston Place. In 1926 Ethel is in the Voters’ Roll at this address, but from 1927 on there is no word of her."
Sorry if this is a bit off topic but it's quite interesting!
