Another quick update -
As I said, there are quite a number of entries for Jessie Toon in the Whitechapel Infirmary. Usually from a Lodging House, on one occasion she was homeless.
Her Age was consistent until it suddenly leapt ten years -
Admitted 23/10/1908, Tune Jessie, 38, Homeless, wid of Frank a Plate layer, suffering from Piles, settlement 2 months, discharged 14.11.08
Admitted 28/01/09 from 84 Brick Lane (own or friends home), Toon Jessie, 49, wid of Frank a Bricklayer, suffering from Fistula, settlement 1 month, discharged 15.05.09
Began to look again as if there might be two Jessies, but it all settled down once more, and at the moment it does appear pretty certain that the Jessie we are looking for is the lady in Lambeth in 1901, as I suggested earlier.
For anyone who might be interested, am attaching what is so far the last entry I've found for her in the Infirmary (haven't gone right to the end of them though) - from the Porter's A+D Register 1911-12. She is number 162, admitted 16/08/1911
And the workhouse entry the day before which mentions her "Brother" Frank McGuire! Admitted from Tilbury, 15/08/1911. What had she been doing there? Had she been there with Frank?
There is still a lot of mystery left though - rather more perhaps than in the Chapman poisoning case - but thats what we like.
If it was Jessie from Devon at the Crown, then what happened to Thomas Toon? The husband who it doesn't appear that she was actually married to. Born 19/01/1859 according to his adult baptism in Lambeth in November 1884. A slightly younger Thomas Toon died in Lambeth in 1903, but that appears to be a Carman from Peterborough and there was a posthumous baptism of a son of his a year later (Funnily enough, on the one occassion the Infirmary record has Jessie's husband as Thomas, he was said to be a Carman!)
What happened to the two daughters of Thomas Toon by his wife Sophia Jane? Sophia Jane Toon, born 27/06/1884 and Elizabeth Caroline Toon, born 05/02/1891. Similarly, Thomas Walter Toon who was one month old in the 1901 census. His birth certificate is at the moment the only known likely source of the identity of Jessie, ie her maiden name.
What happened between the very end of March 1901 and Jessie's arrival in the Borough? She must have been there not too long after.
Who was Frank Mcguire or Macquire? Could he even have been her husband Thomas under an alias? Seems rather unlikely.
