*I NEED HELP W/a CARD* in ♥ The best of me to you ♥

I really hate to do this but I need some help! I got this card in the mail today from a Alex and Mary some place on the East coast b/c the post mark is from METRO,NJ The card was made for me and they also know Hermione there is no return address? It looks like there was a return address at some point but it was removed and there is no last name for Alex and Mary on the card and I really have NO CLUE who sent it at all and I feel bad b/c it’s a very nice card and they took the time to have it made....If you sent this card will you please let me know who you are.....It was sent to my house in Washington,UT It’s one of the best cards I have ever gotten,I just have no clue who Alex and Mary are....No doubt it’s someone I know by another name…
