Olelkovich
Polish princely family
The House of Olelkovich was a princely family from the Grand Duchy of Lithuania in the 15th and 16th centuries. Their main possession was the Duchy of Slutsk–Kapyl. They are sometimes known as Slutskys. They were descended from the Lithuanian Gediminids (male line) and Ruthenian Rurikids (female line). According to the 1528 military census, the family was the fourth wealthiest magnate family in the Grand Duchy. However, its influence declined after the Union of Lublin (1569). The last member of the family was Zofia Olelkowicz (1585–1612), wife of Janusz Radziwiłł. She was elevated to sainthood in the Eastern Orthodox Church in 1983. As part of her marriage negotiations, she insisted on remaining a member of the Eastern Orthodox Church, despite her future husband's allegiance to Calvinism. She died in childbirth, as did the child.

Why this record matters
The phrase “polish princely family” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 22, 2026. The linked authority identifier is Q2668904. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1528, 1569, 1585 and 1612.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
