Marschall moves to Villa Park on-loan to the end of the season.
He told the club's website: “I'm really excited to be here, it's a great Club and I've heard good things from players that have been here previously.
“I'm a goalkeeper that likes to use my feet a lot and play football, it's been the same for me throughout my time at Aston Villa and Gateshead. I like to play out from the back, and I know Mike (Williamson), Busty (Ian Watson) and Belly (Chris Bell) like to do the same here.
“At the same time, we also can't look away from the fact that I'm also here to make saves and be reliable. I'm hoping to bring all of that here.
“I've been playing senior football for a good period of time now and I'm going to try and use my experiences gained so far and my qualities to try and help the team anyway I can."
