The actual Aramis was named Henri d'Aramitz, of the Aramitz family which dated as far back as the 13th century. He was a squire and a lay abbot of Espalungue and Aramitz in Béarn- however, he was not Catholic, but rather Protestant. He was also a nephew of Treville.
He entered the company of the Musketeers around 1640, which means it is possible that he knew Athos. However, the company was dissolved by Mazarin in 1646 and he did not enter another regiment. Instead, in early 1650, he entered a marriage contract with Jeanne de Béarn-Bonasse, an heiress also of the old nobility. He then fathered four children. He traveled to Paris in 1657- for what reason, no one knows- and returned without event. We do not know how he died, but it seems he lived a relatively long and happy life with his family.
