In short
Your name in Hebrew letters is רוזמרי. The name is the English word for the plant rosemary, from Latin “ros marinus”, “dew of the sea”. It has been used as a first name since the 19th century. This form of the name is used in English-speaking countries. In Hebrew it is written by sound. Adding up the numbers of its letters gives 463. That number points to Torah page 109 of 354 — in the portion Bo. What that portion is about: Locusts, darkness and the death of the firstborn; the Passover lamb; the exodus from Egypt; the commandment of tefillin. The verse that begins with the first letter of your name and ends with the last is Exodus 16:29. Each of these steps is laid out below with its sources. Every figure can be checked by hand.

Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 463.
Reduced, each letter to one digit (mispar katan) — 22. A Torah word with the same number is יחד — “together” (Genesis 13:6).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 76. A Torah word with the same number is עבד — “servant” (Genesis 9:25).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1839.
Squares of the letter values (mispar perati) — 81785.
Building: the sum grows with each letter (mispar bone’eh) — 1788.
The letters that come out are גפעיגמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 206. A Torah word with the same number is דבר — “to speak” (Genesis 8:15).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1199.
The number 463 appears in the classical books 1 time across 1 work. The earliest mention is שער הפסוקים (~1573).
The name רוזמרי does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For רוזמרי these are ר and י. The Pentateuch has 2 such verses. The first of them is Exodus 16:29:
ראו כי ה׳ נתן לכם השבת על כן הוא נתן לכם ביום הששי לחם יומים שבו איש תחתיו אל יצא איש ממקמו ביום השביעי
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
