parse("Maria Kowalska z domu Nowak") cannot reach the Polish maiden marker — markers do not compose the way suffixes do

[derek73]

The Polish maiden marker "z domu" (lit. "of the house [of]") is two tokens, and unlike multi-word post-nominals it cannot be reached by adding its component words to the vocabulary.

parse("Maria Kowalska z domu Nowak")
# stock                          -> given='Maria', middle='Kowalska z domu', family='Nowak'
# + 'z','domu' in maiden_markers -> given='Maria', family='Kowalska', maiden='domu Nowak'

The first marker word is consumed as the marker and the second leaks into the maiden name.

Why this is not the same as multi-word suffixes

Adjacent suffix tokens are reassembled by a run predicate (is_wholly_suffix, nameparser/_pipeline/_vocab.py:246), which is why parse("John Smith, MD PhD").suffix is 'MD PhD' and why a two-word credential is reachable as its component words. Maiden markers have no equivalent — a marker matches one word and the extraction begins immediately after it.

So the multi-token question that #291 was carrying for markers does not dissolve the way it did for suffixes. It needs its own answer: either a marker run predicate, or an explicit decision that markers stay single-word and "z domu" stays out.

Provenance

Descoped from 2.0 (#274) and folded into #291 on 2026-07-27 as "pending the multi-token matching decision". #291 is closed as working-as-designed, so this carries the question forward. Recorded in docs/design/decisions.md under Excluded (MAIDEN_MARKERS), which should point here once this is decided.

Currently noted only in nameparser/config/maiden_markers.py's docstring.
