Mr. and Mrs. Chester Loas? Loos? Foas? Foos?

I can't quite figure out the last name of these people. The back of the photo is handwriting "Mr & Mrs. Chester .." and it looks like LOAS. I'm not sure.

Please note: I am in no way related to anyone in the photo, and I do not know where the photo came from, as it came from a "bunch" that I bought somewhere possibly ebay or goodwill.com
Thanks!
