My first game I got married to http://elderscrolls.wikia.com/wiki/Brelyna_Maryon because she had a lovable voice and was a kick ass follower, and you know we were young and in college.
I decided that Taarie was a [censored] and didn't care that a glitch prevented my high elf from marrying her. So I went for Brelyna Maryon. As you said she's lovable. We eventually moved into the house in Windhelm, in mostly due to the ambundent number of display items and partly a svck it to the Nords there.
is it possible to marry Grelod using console?? if so, i'm doing that
Yes.
And what a sweet lass she is
No-one. There really isnt any point. There are no real advantages or disadvantages to it other than a minor buff that I really dont need.
