Vintage Greeting

This vintage postcard, found in one of our local antique malls,  says Merry Christmas even after all these years.  It's dated 1923.  Does anybody know of a  Miss Bertha McElroy of Hillsboro?

The message reads:  "We are all well.  Hoping you are the same.  Did you get my last letter?  Why don't you write?  Have been looking everyday for a letter.  Wish I could be at your house for Xmas dinner.  Minnie D"  Don't you know Minnie would have  LoVeD  facebook?!?
