  Bertha was the daughter/heiress of Conan, reigning Duke of Brittany. The History of the Crawford Family, published in Our Ancestors: Editor: Miss Pauline Young, Box 129 Liberty S.C., Jan., 1953, Vol 1, No. 10 gives her lineage
  
  Bertha was the great granddaughter of William the Conqueror and his wife Mathilda, daughter of Baldwin V, Count of Flanders, who was 5th in Descent from Ethelwida, daughter of Alfred the great, and 10th in descent from Charlemagne. Comparing the Crawford Coat-of-arms with the one of Brittany bears out this claim.

Bertha was the eldest daughter of Conan III of Brittany by Maude, the illegitimate daughter of King Henry I of England.[1] She was the last member of the Breton House of Cornouaille to reign over Brittany.
  
  Life
  Bertha was the daughter of Duke Conan III of Brittany. She married the son of Stephen of Treguier, Alan the Black[2] and she lived in England with Alan until his death in 1146. Alan would eventually become Earl of Richmond. After Alan's death she returned to Brittany as Dowager Countess of Richmond and eventually married Odo, Viscount of Porhoet. When her father Duke Conan III died, on his deathbed Conan III renounced Bertha's brother Hoèl as heir,[2] and designated Bertha as his heiress. On Conan III's death she became hereditary Duchess of Brittany.[3]
  
  Family
  In her first marriage, by 1138, Bertha was married to Alan le Noir [a]
  
  Bertha and Alan had three children:
  Conan IV, Duke of Brittany, b. 1138, their son and heir, as Duke of Brittany and Earl of Richmond[3]
  Constance, who married Alan III, Viscount of Rohan
  Enoguen, abbess of St. Sulpice

  Footnotes
  Alan le Noir was Count of Penthièvre. He was created 1st Earl of Richmond by Stephen of England for his support against the dispossessed Empress Matilda during the English Civil War.[4] The marriage between Bertha and Alan may have been intended to bring Brittany into the English Civil War on the side of Stephen.
  
  War broke out between Bertha's son Conan IV, Duke of Brittany and her second husband Odo. Odo may have made a compact with his brother-in-law, Hoel of Nantes to divide Brittany between them. However in late 1156 Conan IV was able to defeat Odo and secure his maternal inheritance.
