I like both names...

My sister's name is Tabitha, and my partner at the time and myself really liked the name Tobias when Tabitha was pregnant. Of course, she also liked the name, as she had never heard it before. She varied it to Tabious (as she didn't want it shortened to Toby) - lesson learnt, don't share the name you have your heart set on

My daughter has a "Tobias" on both sides of her family - both my current partner and I have nephews by that name
