Marya Seaworth

Marya Seaworth is the wife of Ser Davos Seaworth and mother of Ser Matthos Seaworth. She does not appear on-screen in the TV series.

Background
Davos saved up enough money through his piracy to purchase a small plot of land. He then found a woman, Marya, kind enough to overlook his trade. She gave him a son they named Matthos. Marya and Davos dreamt that eventually he would be able to quit smuggling.

Season 2
Davos mentions that Matthos is acting like his mother is trying to get him to learn how to read and expand his thinking on religion.

Melisandre asks Davos if he loves his wife to which he replies he does. She asks if he has known other women and Davos tells her not to talk about his wife. Melisandre says that she is speaking of other women like herself and asserts that Davos wants her.

Season 3
Salladhor Saan tells Davos to return to Marya Seaworth when he is recovered after the Battle of Blackwater Bay so Davos can comfort her following Matthos' death, but Davos asks to be taken to Dragonstone to stop Melisandre. Salladhor agrees, but to emphasize his belief that Davos will be killed, Sallador promises him to gather up his bones so that Marya Seaworth can wear them around her neck.

In the books
In the A Song of Ice and Fire novels, Marya is the daughter of a common carpenter. She has seven sons with Davos: Dale, Allard, Matthos, Marc, Devan, Stannis, and Steffon. While Davos went with Stannis' household to Dragonstone, Marya remained at the family keep in Cape Wrath to raise their two youngest sons. Of Marya's other five sons, only Devan survived after the Battle of the Blackwater.
