She has conflicting parents connected.
The notes in her About section state her father was William:
She was baptised at Allhallows, Bread St;, City of London on 16 Mar 1599/1600, the daughter of Mr William Brett, merchant taylor. ref: The Registers of All Hallows, Bread Street, and of St John the Evangelist, Friday Street, London. Bannerman W B (Ed.). Publications of the Harleian Society, Registers - Vol XLIII, 1913. Archive.Org
This source also lists William as her father:

So, I'm going to disconnect Thomas Brett as her father since that doesn't seem to be supported.
