Edward Guinness—the real‑life Edward Cecil Guinness, 1st Earl of Iveagh—married Adelaide Maria Guinness , his third cousin, in 1873.

Who Adelaide Maria Guinness was

  • Adelaide was also a member of the Guinness family, from the banking branch, and the daughter of barrister and MP Richard Guinness.
  • Within the family she was affectionately known as “Dodo” , a nickname whose exact origin is unclear.

Their marriage and children

  • Edward and Adelaide had three sons :
    • Rupert Edward Cecil Lee Guinness
    • Arthur Ernest Guinness
    • Walter Edward Guinness
  • Their marriage lasted until Adelaide’s death in 1916 at age 72; Edward never remarried and died in 1927.

How this fits with House of Guinness

  • The Netflix series House of Guinness dramatizes Edward’s romance with a fictional character, Ellen Cochrane, but historically he remained married to Adelaide , and they are portrayed as having a long, politically and socially influential partnership.

If you’re asking about a different Edward Guinness (for example, a later Earl), feel free to clarify the full name or generation and I can narrow it down.
