This Euphemia is supposedly a direct ancestor for me, so I've been trying to find better documentation of which John Graham was her father. Her profile notes state:
Notes ◦Father identified as "Sir John Graham". She could be daughter of either of the Sir John's in that time frame;
Sir John Graham of Abercorn, 9th Earl of Menteith executed 28.02.1347 after the battle of Durham.
Sir John Graham of Dundaff b c1245 d.22.07.1289 killed at Battle of Falkirk.
As her husbands father died 1297 the dates suggests she is more likely a daughter of the Sir John of Dundaff who died 1289.-Ed.
Died: ◦Y
Sources 1.[S541] Stirnet Genealogy, Peter Barns-Graham, Lundin1 (Reliability: 3)
which indicates she's connected to the wrong parents here on Geni.
The only other reference I found to her father was this:
http://www.lundie.org/newsite/lundie_of_that_ilk/lairds/lundie_lund...
which states:
Sir Richard is believed to have married Margaret de Dunbar, daughter of Patrick Dunbar, Earl of Dunbar and Marjorie Comyn, herself the daughter of Alexander Comyn, Earl of Buchan. He was succeeded by his son Walter, who married Euphemia Graham, daughter of Sir John Graham.

In my opinion, the John Graham connected as her father here on Geni was a more noteworthy man than to just say Euphemia was his daughter and not have any further info connected to him at the link above than a comment about a generic Sir John Graham. Where a parent is noteworthy, there is usually something like '....daughter of Sir John Graham who (and then would list his titles or accomplishments that made him noteworthy, perhaps even his dates'. Instead, there is nothing.
The Wikipedia page for the John Graham connected as her father doesn't have her listed as one of his children on his Wikipedia page:
https://en.wikipedia.org/wiki/John_de_Graham
only lists one child for John and his Halliday wife, a son also named John, no daughter(s) at all
