I can understand why you would be upset

. When our SIL was pregnant she told me she liked Jackson but spelt Jaxon and I obviously like Jackson. She was pregnant and I had just MC'ed so I was praying that she was having a girl, thankfully she did.
But I also agree that Heidi and Chloe are totally different. Names are just that, names, and will be used by others no matter how unique we try to make our own childrens.
I think as the girls get older they will use it as having something in common
