Hi Rob, I've just recently started looking into the history of Sean and Patrick Doyle and found out that a cousin of mine did a school project for her leaving cert on this last year (she's a lot younger than me!). Anyway, as part of her research she got various documents related to the two brothers from several sources (eg. Dept of Defense, Allen library, Pensions Dept. etc.) I've gotten hold of copies of some of it. While I don't have all the actual documents relating to the information you're looking for, the Dept of Defense supplied a summary/cover letter detailing documents/correspondence in relation to Patrick Doyle that they have (mostly to do with requests for medals, widows pensions, education grants for kids), which allows me to piece together some of the info you're looking for, which I will list below. Some other info can be found in a book by Tim Carey "Hanged for Ireland - The forgotten Ten" published by Blackwater press (ISBN 9781841315478);
1. Louisa married Pat Doyle in 1916. Her maiden name was Herbert. She was from Glasgow (from book).
2. First child born 1917. Chistened Catherine Constance (after Constance de Markievicz) but was called Kathleen. (from book).
3. Second child born 1919 (Patrick). Died of pneumonia 1920. (from book).
4. Feb 27 1921. Twin girls born (Eilish and Louisa Patricia). Louisa Patricia died 12 March 1921 in her mothers arms on Berkely Road while returning from Mountjoy prison following first/last visit to Pat before execution (she was buried in Kilbarrack on the morning of Pat's execution). (from book - except Ailish is not named........that came from my mother).
5. Louis remarried in Oct 1928 (Albert Brock) (from Dept of Defense cover letter).
6. There's also a reference in the DoD summary of a letter from Kathleen Doyle-Bolger , dated 13th of July, making a request for an army pension (which seems to answer your question about whether the children changed their name to Brock - looks like they didn't).
7. My mother thinks that Louisa and Albert Brock did not have children but think that they may have adopted a child called Betty?
8. I've uploaded (I hope) a photo from the book of Louisa and Kathleen (and baby Eilish). If it doesn't work and you'd like the photo I can email it to you.
That's all I have - don't know what became of Albert Brock but Kathleen Doyle-Bolger died sometime in the early eighties as far as I know. If there's any specific questions you have, let me know and I'll see what I can find out - I've been driving my mother round the bend with random questions lately and I've figured out the more specific I can be, the better.
Hope this is of some help!
