Sometime in the past before the events of SAO occurred, Grimlock married Griselda and they were happy together for a while.

Sword Art Online
====Murder Case in the Area He was the culprit of his in-game and real-life wife, Griselda's death. He killed her because he did not like the change in her personality. At first he didn't want to aid Caynz and Yolko in their plans to catch Griselda's killer by forging them weapons to use in the in-AREA murders, but eventually he did, but not with good intentions. He helped so he could have Caynz, Yolko and Scmitt together and get them killed with the help of the infamous red guild, Laughing Coffin. However, the plan failed, because Kirito realized the truth of Griselda's death in time, and came to rescue Caynz and Yolko. Grimlock is then caught by Asuna.

It is unknown to what happened to him in the remaining time of SAO, but in the end, he is assumed to be logged out or died.
