* The Peerage uses both surnames for them, as does Cracroft's Peerage. Marlyn Lewis, citing numerous Douglas Richardson sources, uses just FitzGerald for Thomas, but both FitzGerald and FitzThomas for Maurice.

Children: : John Burke, in ''A Genealogical and Heraldic History of the Commoners of Great Britain and Ireland Enjoying Territorial Possessions Or High Official Rank, But Uninvested with Heritable Honours, Volume 3'', includes kids John, Roger, and Adomar, giving them to Darcy's first wife, Emeline. Then includes kids William and Elizabeth, giving them to Joan.
* The Peerage, citing ''BP2003 volume 1'', includes kids John, an unknown son, and 2 unknown daughters, giving them to Emmeline. Then includes kids Elizabeth, Aymer, Roger, and William, giving them to Joan.
* Marlyn Lewis, citing numerous Douglas Richardson sources, gives Joan Thomas, John, Adam, Elizabeth, and William, mentioning only John, for Emmeline. 2 Johns, Joan's dying without issue, and Emeline's being the surviving heir of his father.
: Daughter Elizabeth's Wiki page states her father had 8 children with his first wife, naming only John, and only mentioning William as a full sibling.
: We've got Thomas as Emeline's son, here. And, are there any sources for Henry?
