Hello, 72.49.39.180, and Welcome to Wikipedia!   

Hi, Thanks for updating the Malvina Gruber article. We don't use ibid on Wikipedia, so i.ve changed it to a ref. Regarding the birth date, you can use the template:efn to place a note in the article saying the sources are varying. You don't put in date of death unknown. Its not used. Hope that helps. scope_creep^Talk 15:11, 24 March 2022 (UTC)[reply]

I like that category you discovered. scope_creep^Talk 15:24, 24 March 2022 (UTC)[reply]

Thank you for your contributions to Wikipedia. It appears that you copied or moved text from Metatron into another page. While you are welcome to re-use Wikipedia's content, here or elsewhere, Wikipedia's licensing does require that you provide attribution to the original contributor(s). When copying within Wikipedia, this is supplied at minimum in an edit summary at the page into which you've copied content, disclosing the copying and linking to the copied page, e.g., copied content from [[page name]]; see that page's history for attribution. It is good practice, especially if copying is extensive, to also place a properly formatted {{copied}} template on the talk pages of the source and destination. Please provide attribution for this duplication if it has not already been supplied by another editor, and if you have copied material between pages before, even if it was a long time ago, you should provide attribution for that also. You can read more about the procedure and the reasons at Wikipedia:Copying within Wikipedia. Thank you. —Compassionate727 ^(T·C) 19:43, 27 March 2022 (UTC)[reply]
