I'm also researching Josephine Fitzgerald because of a Neville/Nevill family connection but I'm fascinated by her relationship with Dorothy Lawrence.
I believe she didn't leave her anything in her will, but I've found a photo of them together and a mention of her in a letter so at some point in 1914-1919 I believe they were close and that Josephine typically used 'foster' daughters. I can't pinpoint when Dorothy was 'fostered' though?
I'd be keen to know especially as it looks like Dorothy accused Josephine's husband of abuse - though by the dates provided he was only her husband for 2 years between 1888-1890 when Dorothy was only 1-2 years old? I suspect that that allegation might have been against someone else that Dorothy was staying with at the time, but if anyone has any evidence of Dorothy and Josephine's time together or a reason for their rift at Josephine's end-of-life I'd appreciate it.
