The name Rosalvo in Hebrew letters is רוזלבו. 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.
רוזלבו
In short
Your name in Hebrew letters is רוזלבו. Adding up the numbers of its letters gives 251 — the same as the Torah word אמרי, “Amorite”. That number points to Torah page 251 of 354 — in the portion Shlach. What that portion is about: The twelve spies; forty years for forty days; challah and tzitzit. The verse that begins with the first letter of your name and ends with the last is Exodus 23:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Rosalvo” — this exact spelling is what was calculated: רוזלבו. 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 רוזלבו gives 251.
251
The number 251 is the Torah word אמרי — «Amorite» (Genesis 10:16).
I am HaShem your G-d, who brought you out of the land of Egypt, to be your G-d: I am HaShem your G-d.'
This is from the portion Shlach. What it is about: The twelve spies; forty years for forty days; challah and tzitzit.
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) — 251. A Torah word with the same number is אמרי — “Amorite” (Genesis 10:16).
Reduced, each letter to one digit (mispar katan) — 26. A Torah word with the same number is והיה — “and it became” (Genesis 2:10).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 53. A Torah word with the same number is אבן — “stone” (Genesis 2:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 973.
Squares of the letter values (mispar perati) — 41025.
Building: the sum grows with each letter (mispar bone’eh) — 1358.
The letters that come out are גפעכשפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 553. A Torah word with the same number is שריגם — “branches” (Genesis 40:10).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1087.
The number 251 appears in the classical books 6 times across 6 works. The earliest mention is בעל הטורים על התורה (~1300).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 251. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

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 רוזלבו 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 רוזלבו these are ר and ו. The Pentateuch has 6 such verses. The first of them is Exodus 23:19:
ראשית בכורי אדמתך תביא בית ה׳ אלהיך לא תבשל גדי בחלב אמו
This is from the portion Mishpatim. What it is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”.
The name רוזלבו has no such day. The numbers of the dates in a year cover 326 values out of 940, and 251 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
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.
