Household Explorer

Every parent pair this archive has reconstructed from the registers, with the children recorded under them. Search a name, drag the year, pick a region — then open a household and walk to the ones it connects to.

A household here is not a guess about a family. It is a set of baptisms that name the same two parents, gathered under those parents and sorted by date. That is the smallest honest unit the registers will give you: a father, a mother, and the children a priest wrote down between two dates in one parish.

Six of these households can be linked to another — a son in one becomes the father in the next, at the right remove, in the right parish. 9 of 52 sit in a chain; the rest float. Households that float are not failures. They are the shape of what survives when a parish's register begins in 1750 and the family arrived in 1700.

How the links were made

A link is drawn only when a child in one household carries the surname, appears as the parent heading another household in the same region, the parishes are compatible, and the gap between the two households falls between 17 and 48 years. Where more than one candidate fits, the link is not drawn at all — those cases are listed as ambiguous rather than resolved by preference. Confidence is strong when the candidate is unique, the parish is the same, and the gap sits between 20 and 45.

What the colours mean

The stripe down the left of each card is the region: Kvarner, Istria, Dalmatia, Tyrol. The word linked appears on any household that stands in a chain.
