The illegitimate York girl

Eleanor Holland was born in 1404 the illegitimate daughter of Constance of York (1374-1416), granddaughter to King Edward III, and Edmund Holland, Earl of Kent (1382-1408).

Edmund of Langley, Constance's father

Eleanor's mother Constance, the daughter of Prince Edmund of Langley, Duke of York, was firstly married to Thomas le Despenser and had three children by him before he died in 1400.
After the death of her first husband, Constance fell in love with Edmund Holland and became his mistress. Eleanor was then born from this union in about 1404.
Constance did not remarry, however Edmund married in 1406 to Lucia Visconti, daughter of the Lord of Milan. Constance attended the wedding banquet and made no protest to the union. Edmund was killed in battle in 1408 in Brittany at the age of twenty-six.

Eleanor brought her case to the Court Christian which was a spiritual court to disprove her illegitimacy in order to lay claim to her father's estate after his death, however she lost her case.
In 1431 the heirs of Edmund Holland; Joan, Duchess of York and Margaret, Duchess of Clarence who were Eleanor's aunts on her father's side, Richard Duke of York, Richard Earl of Salisbury, Alice his wife, Ralph Earl of Westmorland, John Lord Tiptoft, Joyce his wife and Henry Grey all collaborated and made a petition to Parliament to prove that Eleanor is illegitimate and to stop her from claiming to be 'the daughter and heir' of her father Edmund Holland despite whatever findings or conclusions the spiritual courts come to, in order to keep her from inheriting any of his estate.
The petition went as follows;

"wherefore þe saide suppliantz, dredyng hem to be hurt and 

enpeched of thair enheretance had be the saide Edmond, be 

other subtilite and wirchyng in þe temporell lawe, to be wroght
