When did "Pensylvania" become "Pennsylvania"?

The Spanish labeled the area L'arcadia, or "wooded coast", during the explorer Verrazano's voyage in in 1524. (This is significant.) After changing hands multiple times, the land was given to Willian Penn by King George II to settle a debt owed to Penn's father by the king. Though Penn suggested Sylvania (Latin: silva/silvestre means woods/forest. Sylvania means woodland.) I seem to remember it was King Charles II who named it Penn's Sylvania (later shortened to Pennsylvania).

Back when the bell was made (actually for many years before and some after), spellings did not matter as much as sounds. The word Pensylvania and other variants all appear on old maps and documents.

This spelling has been used to illustrate the doctrine of idem sonans in law, which provides that the misspelling of a name is acceptable on a deed so long as it sounds enough like the owner's name. Similarly, in the first line of the "Frame of Government of Pennsylvania adopted May 5, 1682," the colony is spelled "Pensilvania." However, it was not so officially named.

The bellmaker, however, copied the name in the quotation, stating "By Order of the Assembly of the Province of Pensylvania for the State House in Philada." No one assumes, however, that Philadelphia was ever actually named Philada. All throughout history, when things were written (or carved, etc.) by hand, especially when they needed to fit into limited space, abbreviations and misspellings are multitudinous.

Medica's statement about the provenance of the name Pennsylvania is absolutely correct.

Pensylvania, however, was an accepted alternative spelling at the time of the casting of the Liberty Bell.

From UShistory.org:

Also inscribed on the Bell is the quotation, "By Order of the Assembly of the Province of Pensylvania for the State House in Philada." Note that the spelling of "Pennsylvania" was not at that time universally adopted. In fact, in the original Constitution, the name of the state is also spelled "Pensylvania." If you get a chance to visit the second floor of Independence Hall in Philadelphia, take a moment to look at the original maps on the wall. They, too, have the state name spelled "Pensylvania" (and the Atlantic Ocean called by the name of that day, "The Western Ocean"). The choice of the quotation was made by Quaker Isaac Norris, speaker of the Assembly.

Per Wikipedia:

At the time, "Pensylvania" was an accepted alternative spelling for "Pennsylvania." That spelling was used by Alexander Hamilton, a graduate of King's College (now Columbia University), in 1787 on the signature page of the United States Constitution.[105]

According to John C. Paige, who wrote a historical study of the bell for the National Park Service.

Per USConstitution.net on misspellings in the constitution:

Only one, though, is a glaringly obvious mistake. In the list of signatories, the word "Pennsylvania" is spelled with a single N: "Pensylvania." This usage conflicts with a prior spelling, at Article 1, Section 2. However, the single N was common usage in the 18th century — the Liberty Bell, for example, has the single N spelling inscribed upon it.

William Penn was the person they named Pennsylvania after, but considering he was Christian and was protested about the war, the bell was named The Liberty Bell of Pensylvania. During the time of the constitutional era, it was believed that the state it's self was spelled as "Pensylvania". But later on in the statehood era, It was renamed Pennsylvania.
