The name Bertille in Hebrew letters is ברטיי. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
ברטיי
In short
Your name in Hebrew letters is ברטיי. Adding up the numbers of its letters gives 231 — the same as the Torah word וצפנה, “and northward”. That number points to Torah page 231 of 354 — in the portion Naso. What that portion is about: The sotah — the test of the wife; the nazirite; the priestly blessing; the gifts of the tribal chiefs for the dedication of the altar. The verse that begins with the first letter of your name and ends with the last is Exodus 19:1. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Bertille” — this exact spelling is what was calculated: ברטיי. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name ברטיי gives 231.
231
The number 231 is the Torah word וצפנה — «and northward» (Genesis 28:14).
And the priest shall wave them for a wave-offering before HaShem; this is holy for the priest, together with the breast of waving and the thigh of heaving; and after that the Nazirite may drink wine.
This is from the portion Naso. What it is about: The sotah — the test of the wife; the nazirite; the priestly blessing; the gifts of the tribal chiefs for the dedication of the altar.
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) — 231. A Torah word with the same number is וצפנה — “and northward” (Genesis 28:14).
Reduced, each letter to one digit (mispar katan) — 15. A Torah word with the same number is זוב — “to flow” (Exodus 3:8).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 51. A Torah word with the same number is אכל — “to eat” (Genesis 2:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 953.
Squares of the letter values (mispar perati) — 40285.
Building: the sum grows with each letter (mispar bone’eh) — 867.
The letters that come out are שגנממ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 433. A Torah word with the same number is משפחה — “family, clan” (Genesis 8:19).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1381.
The number 231 appears in the classical books 13 times across 5 works. The earliest mention is מדרש לפירושים (~1450?).

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name ברטיי 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 ברטיי these are ב and י. The Pentateuch has 16 such verses. The first of them is Exodus 19:1:
בחדש השלישי לצאת בני ישראל מארץ מצרים ביום הזה באו מדבר סיני
This is from the portion Yitro. What it is about: Jethro's counsel on judges; standing at Sinai; the Ten Utterances; “you shall not make yourself an idol”.
«And the priest shall wave them for a wave-offering before HaShem; this is holy for the priest, together with the breast of waving and the thigh of heaving; and after that the Nazirite may drink wine.»
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
