pereliinseid

I’m not certain what "pereliinseid" refers to. The term does not appear to be a widely recognized topic in Estonian sources, and I want to avoid fabricating information. Could you please provide more context or confirm the spelling? For example, is it a fictional concept, a regional term, or a specific field (biology, sociology, linguistics, etc.)? If you can share what you want the article to cover or the intended meaning, I can write a neutral, concise wiki-style entry under 300 words. If you’d prefer, I can also draft a general article about kinship terminology in Estonian or about a closely related real topic.
