In the profile summary of Feigel bat Majer Halevi, the question is this: Is her father's surname Grayding or was he from Grayding (Graydong).
To add on what's written in the unbroken chain:
In the book לוחות זכרון: ספר כולל תולדות רבני העיר קראקא
A brief biography is written on Rabbi Hirsch, and it says that Feigel was daughter of Meir ABD Grayding. As to say that it's his place of Rabbanut and not his surname.
I've added an image from the book in the media tab of Feigel.
