曾祖母

My great-great-grandmother had Down syndrome (”Mongolism” as they called it in her day).

我的母有唐氏症（他们时候将之成为蒙古症）。

The brooch is a family heirloom which came down to her from her great-grandmother.

这枚胸针是家的家宝，是从母一手中的。

This pair of bracelets were handed down from my greatgrandmother.

这副手镯是我母下来的。
