Did Maymunah bint al-Harith only ever marry Prophet Muhammad?

The Prophet's 11 wives are: 1. Khadijah ◊,‡ 2. Sawda ◊,‡ 3. Aisha 4. Hafsa ‡ 5. Zaynab bint Khuzayma ‡ 6. Umm Salama ◊,‡ 7. Zaynab bint Jahsh ‡ 8. Juwayriyah ‡ 9. Ramlah ‡ 10. Safiyah ‡ 11. Maymunah . (And some contested wives: https://islam.stackexchange.com/q/37553/17163). The footnotes are based on what's at the Wikipedia pages: ◊ Had a child (or children) prior to marriage with Muhammad. ‡ Had a husband prior to marriage with Muhammad. (If I've done my homework correctly.) Surely Aisha was too young for a prior marriage when she married Muhammad. But I'm unsure about Maymunah. So... **Question**: Did Maymunah bint al-Harith only ever marry Prophet Muhammad? A former husband is not listed on her Wikipedia page . Islam.Wikia.com write: "After the Prophet's death, (peace and blessings of Allah be upon him) Maymuna continued to live in Medina for another forty years, dying at the age of eighty..." which means she married Muhammad at around 40 years of age.
