I'm trying to trace any descendants of a Joanna Maria Tissera of old Ceylon. Some of her descendants had the surname of Collom in the late 1800s and early 1900s but of course they intermarried. (My paternal grandmother was a Collom who married a Kelaart) This woman (Tissera) wrote a very interesting Fideicommisum will which was only accessed by the sixth generation after her. I am part of that sixth generation and would really like to make contact with anyone who knows about this luminous and astute business woman. Apparently she was very wealthy. Stories about are are legend... one said she owned land in Colombo, including a stretch of property that incorporated Galle Face Green, and also that she owned Nigris Building in Fort. My research shows she was probably a Colombo Chetty, Catholic woman. Further research shows that the name Tissera was Jewish in origin. I would love to hear from anyone who has ancestral links to her.
