how old was mary

There isn’t enough information in your question to say how old “Mary” was, because many well‑known people are named Mary (for example, Mary the mother of Jesus, Mary I of England, various celebrities, or even a private person in a forum discussion).

Clarifying which Mary

To give an accurate age, it is necessary to know at least one of the following:

• Full name or a clear identifier (for example, “Mary, the mother of Jesus” or “Queen Mary I of England”).

• A context such as: historical figure, TV character, celebrity, or someone from a specific forum/thread.

Without that, any answer would be guesswork and could easily be wrong.

How you can refine the question

Please specify:

• Which Mary you mean (e.g., “Mary the mother of Jesus,” “Mary I (Bloody Mary),” “Mary from Downton Abbey,” or another Mary).
• If it’s a less famous person, any available public context (for example, a public figure with their surname).

Once you clarify which Mary you have in mind, a concrete, well‑sourced age estimate or exact age can be provided.
