These are my rough calculations, which can be adjusted 1 or 2 years either way....
Ana Pérez Calzadilla nacida cerca 1679 which would make her about 45 when she dies giving birth to Maria in about 1724.
Maria Garcia de Calzadilla c.m. cerca 1665 con Juan Simon.
Maria nacida cerca 1638 (which makes her 41 a nacida de Ana)
Maria Hernandez de Romera c.m. cerca 1620 con Simon Pérez.
Maria nacida cerca 1596 (which makes her 42 a nacida de Maria Garcia de C)
If Beatriz was say 18 when she married, she would be 40 cuando Maria Ana nació.

Very reasonable calculation observed by prima Veronic Ihlenfeldt, from AU.
