This is my great great grandparents marriage certificate.

I am at a roadblock with my research for the father of the bride's side of the family because I can't decipher his name.  I can tell the last name is Johnston. I have found other records where the daughter (bride) states that she is of Danish decent.  It is known in my family that this line is also of Icelandic decent.

I can't tell what his name is. Astmery Astney Adney Admey...I just don't know.  Most of the names I've come up with don't even seem to be names.
I do believe that the first letter starts with an A and ends with a y.

Maybe is is a shortened form of a name?  Any help or brainstorming would be much appreciated!

Thank you in advance,

Michelle
