How long was Edgar allan poe married to Virginia clemm?

Edgar Allan Poe was 27 when he married his 13 year old cousin Virginia Eliza Clemm. They were related because David Poe Jr (Edgar's father) and Maria Clemm (Virginia's mother) were brother and sister. Marrying at a young age was quite common considering that not many medicines were available at that time and you didn't live very long. After eleven years of marriage, Virginia died of tuberculosis.
