I am trying to wrap my head around a tricky wedding party from a marriage record in Northern Alsace, 1796. The bride's name is Dorothea Neufarth, her parents are given as Georg Neufarth and Anna Maria Zwolle, and they are accompanied by two witnesses, a Peter Altermatt, and a Valentin Hart. So far, so good. However, the record then goes on to say that the bride was born out of wedlock, that Peter Altermatt is her brother, and Valentin Hart is her guardian. (Huh?) I wonder about the brother's last name, and am curious if there is any secondary information I might glean from this record.
The record is pretty long and I cannot download it properly, so I only provide a link for anyone who might want to look for themselves: http://archives.bas-rhin.fr/detail-document/ETAT-CIVIL-C42-P1-R47835#visio/page:ETAT-CIVIL-C42-P1-R47835-2923914
