sister-in-law Catharina Swalmius buried

Date: 
December 31, 1674

The burial record of Catharina, the sister of Leeuwenhoek's new wife Cornelia, states that she was living on the Hippolytusbuurt when she died and was buried in the Oude Kerk. If that was Leeuwenhoek's house, as seems likely, had the never-married Catharina been living there since the marriage of her sister four years ealier? Had she come only at the end of her life to be nursed by her sister?

In Cornelia's will of October 1671, she mentioned Catharina.
