Her first husband died in 1102 and she acted as regent for their minor sons until the end of 1111.
Correction

This sentence is off by about a year on both points: Roger I died in 1101, and standard reference works describe Adelaide's regency as lasting until 1112, not ending in 1111.

Full reasoning

Reliable reference works contradict both dates in this sentence.

  • Roger I of Sicily died in 1101, not 1102. Britannica dates his death to June 22, 1101.
  • Adelaide's regency is commonly dated 1101–1112, not 'until the end of 1111'. Encyclopedia.com's biographical entry on Adelaide describes her as having "Reigned 1101–1112", and Cambridge University Press's Roger II of Sicily timeline likewise lists "1101 Death of Roger I; regency of Adelaide del Vasto" followed by "1112" as the end of that regency.

So the article's wording makes Roger's death one year too late and shortens Adelaide's regency by about a year.
