> If a living transgender or non-binary person was not notable under a former name (a deadname), it should not be included in any page (including lists, redirects, disambiguation pages, category names, templates, etc.), even in quotations, even if reliable sourcing exists. Treat the pre-notability name as a privacy interest separate from (and often greater than) the person's current name.

So, now she has passed away, it is allowed by policy to add her birth name to the article (assuming it can be reliably sourced, etc)

Although https://en.wikipedia.org/wiki/WP:BDP also says:

> Generally, this policy does not apply to material concerning people who are confirmed dead by reliable sources. The only exception would be for people who have recently died, in which case the policy can extend for an indeterminate period beyond the date of death—six months, one year, two years at the outside.

So some might argue that, due to WP:BDP, WP:DEADNAME still applies in the period immediately after her death – but in 2027 it won't (assuming Wikipedia leaves its policies unchanged)

> Former, pre-transition names may only be included if the person was notable while using the name; outside of the main biographical article, such names should only appear once, in a footnote or parentheses.

There's a conversation to be had about whether the decisions Wikipedia has made about prior names and consistent use of pronouns in the biography of trans persons is the correct one for an encyclopedia. But this is definitely not the place or time to have that conversation.
