Cilla Michaelis

Yad Vashem testimony by brother-in-law Fritz Pagel in 1979:
https://yvng.yadvashem.org/index.html?language=en&s_id=&s_lastName=...
DOB is given as 29.10.1890, Dirschau.
There is no MICHAELIS, born Dirschau, with this DOB in Gedenkbuch.
But we know that his testimonies for her sisters Frieda and Therese have (slightly) incorrect DOBs.
MtL has only 15 MICHAELIS persons born Dirschau; and the only one who comes close to Cilla name is Caecilie STORCH, born MICHAELIS. She married 1934 (aged 48), with witness Alfons (?) Michaelis, aged 49.

We make the assumption that 'Cilla' is a different person to Caecilie, and that she is incorrectly omitted from Gedenkbuch..
