When the famous bishop of Lund, Peder Winstrup, died in 1679 he was laid to rest in a family crypt in Lund Cathedral alongside his wife. Following a restoration of the Cathedral in the late 19th century, Peder Winstrup’s coffin was moved to the crypt, as the family grave was dismantled. In 2012, a decision was made to move his remains to a different location presenting scientists with an opportunity to investigate bishop’s mummified remains. Unexpectedly, hidden underneath Winstrup’s body, a small bundle containing mummified remains of a 5–6-month-old foetus was found. This finding prompted questions regarding the possible relation between both individuals with most hypotheses suggesting no relation and an opportunistic character of the placement of the foetus in bishop’s coffin. Here we test the hypotheses using ancient DNA genomics, including mitochondrial DNA and Y chromosome data, as tools for kinship analyses. We identified a second-degree kinship relation, which, in combination with genealogical analysis, suggests a grandparent-grandchild relation, as highly probable affiliation.

当隆德的著名主教Peder Winstrup于1679年去世时，他与妻子一起被放在隆德大教堂的一个家庭地下室里休息。在19世纪后期对大教堂进行修复之后，随着家庭墓地的拆除，皮德·温斯特鲁普（Peder Winstrup）的棺材被移到了地下室。2012年，决定将其遗体移至其他地点，这为科学家们提供了机会来调查主教的木乃伊残骸。出乎意料的是，发现它藏在Winstrup的身体下方，里面有一小包，里面装有5-6个月大胎儿的木乃伊。这一发现引发了有关两个假设之间的可能关系的疑问，大多数假设表明没有关系，并且主教棺材中胎儿的放置具有机会主义特征。在这里，我们使用古老的DNA基因组学来检验假设，包括线粒体DNA和Y染色体数据，作为亲缘关系分析的工具。我们确定了二级亲属关系，再结合家谱分析，表明祖父母与孙子女关系是高度可能的从属关系。
