This looks like a very interesting article. I have made some comments below. I haven't yet checked the sources, but will do this after the nominator has had a chance to respond to my initial feedback. Best wishes Mertbiol (talk) 09:50, 26 July 2023 (UTC)[reply]
For an article of this length, the lead section is too short. I would typically expect two paragraphs of 3-4 sentences each. I would suggest mentioning her activities after the Spanish-American War, including her work with sufferers of Spanish Flu and leprosy.
I suggest moving the comma in the first sentence from after "sister" to before "who".
I suggest rephrasing the first sentence to read "Ellen "Nellie" Purtell was born on November 14, 1866, in Monches, Wisconsin. (Starting a section with "She" is not good style.)
"Monches, Wisconsin" needs a link. Is Merton, Wisconsin appropriate?
There is no mention of her change of name to "Regina". Was this a name that she adopted when she became a nursing sister?
Please link Theodore Roosevelt as this is the first mention in the main body of the article.
Would you be able to rewrite the first sentence of the first paragraph, so that the phrase "She was widely beloved" is attributed please? Something like - "According to the historian X, Purtell was "widely beloved"". An exact quote would be useful here. (WP:NPOV applies.)
@Mertbiol, I am so honored that you took the time and did such a careful and beautiful job! I'm a new-ish editor, and happy to learn from you. Right now I'm on vacation in Boston, but I'll be able to focus on this article soon. I'll go through each change you suggest and update the whole thing. Then I'll ping you to see if it works for you.

@Mertbiol, have a look now. I need to go through your list one more time to make sure I got everything, so don't bother listing it if I missed something, just say "look again" or something like it. I am blown away by how thorough your edit was! I'm an author, and I learned a lot from you today. Going forward I will remember what you taught me. Fortunaa (talk) 22:11, 14 August 2023 (UTC)[reply]
I have checked the following sources: [3] (see note below), [11], [12], [13], [14] (see note below) and [19] (see note below).
Ref [2] (Mitchell, Dawn 2015) - per MOS:LEADCITE this reference should be moved from the lead section into the main body of the article. (I will allow ref [1] to remain in the lead, as it is attributing a quotation.)
Ref [3] (Monroe News-Star) - gives birth year as 1866, but does not give Purtell's birth date. Please provide an additional citation to support the birth date.
Ref [14] (Hospital Progress) - says "for many years afterwards these parents kept in contact with her" - does not say "many of those families remained in contact with her for the rest of her life". Please rephrase or provide an additional citation to support this assertion.
Ref [19] (Ascension DePaul Services) - does not mention Purtell at all. Please provide an additional citation to support "Ill health forced her into retirement, and she spent much of that time writing letters to fundraise for foreign missions in India, Japan, China, and elsewhere. She initially lived in a retirement wing of the Providence Infirmary. However, it was demolished, so the sisters transferred her to the DePaul Sanitarium in New Orleans, Louisiana"
@Mertbiol, yay! You are the best editor, a true gift. Here are my responses:
Ref [2] (Mitchell, Dawn 2015) - per MOS:LEADCITE this reference should be moved from the lead section into the main body of the article. (I will allow ref [1] to remain in the lead, as it is attributing a quotation.) GOT IT!
Ref [3] (Monroe News-Star) - gives birth year as 1866, but does not give Purtell's birth date. Please provide an additional citation to support the birth date. I FOUND A WONDERFUL NEW SOURCE, THEDE ANDREIN, AND ADDED IT. PLEASE SEE MY NOTES ON THE EDITS.
Ref [14] (Hospital Progress) - says "for many years afterwards these parents kept in contact with her" - does not say "many of those families remained in contact with her for the rest of her life". Please rephrase or provide an additional citation to support this assertion. I DELETED THE OVERSTATEMENT.
Ref [19] (Ascension DePaul Services) - does not mention Purtell at all. Please provide an additional citation to support "Ill health forced her into retirement, and she spent much of that time writing letters to fundraise for foreign missions in India, Japan, China, and elsewhere. She initially lived in a retirement wing of the Providence Infirmary. However, it was demolished, so the sisters transferred her to the DePaul Sanitarium in New Orleans, Louisiana" ARGH! THEY CHANGED THE WEB PAGE. I FOUND NEW SUPPORT FOR THESE.
Please also note that your questions gave me rich new data, including the John Philip Sousa story which is lovely. I seek a backup source for that, because I don't want to repeat legends, ever.
I am SO GRATEFUL to you. We writers dream of such editors, and I hope what goes around comes around and you find great ones for your own work as well.
@Mertbiol, I am so honored! You were a tough judge, and it was a privilege to engage your high standards. After this I will edit my other new articles to try and bring them up to the principles you have modeled in your careful process. All of the work in my portfolio will benefit from your time and care. Abundant thanks to you, always. Fortunaa (talk) 12:18, 20 August 2023 (UTC)[reply]
