We now know the names of the three people who died after their Fairview townhouse caught fire early Friday morning.

Amy Miller, 31, and her two children, Isaiah and Lily, were unable to escape their home as flames spread.

"Amy was such a positive, beautiful woman and such a good mom," Barbara Miller, a former employer of Amy's, said in a phone interview Sunday. 

The Anchorage Fire Department began receiving calls about the fire around 1:30 a.m. Friday.

About 25 units responded to the two-alarm fire, which was in a row of townhomes, according to AFD.

"Amy was a wonderful daughter, mother, sister and friend to everyone she met," family spokesperson Natalie Forbis said. "She was adored by everyone and I treated her children as my own grandchildren."

Midnight Sun Brewing Company, where Miller once worked, is in the early stages of putting together a fundraiser for the family.

"MSBC will be organizing something to fundraise and/or collect donations for her family and displaced fire victims," vice-president and co-founder Barbara Miller said via Facebook.

"My heart is broken. One of our former employees, Amy Miller, and her two young children passed away this morning in the Fairview townhouse fire that also left 17 people displaced. Amy was such a beautiful, strong, positive spirit. This cannot be real, right?  This situation is tragic."

"I remember her as a happy, positive person," Barbara Miller said Sunday. 

The family has put together a YouCaring page with more information and ways to help the family.

The cause of the fire has not yet been determined. AFD fire marshal Cleo Hill said Friday that the fire "doesn't appear to be suspicious."

A family of nine who lived in a townhouse adjacent to the fire was displaced because of damage to their home. 

The Red Cross of Alaska said Friday it was assisting 17 people affected by the fire.
