Skyz, asking your rabbi is a great idea.
You can’t believe everything (or most of) the information you find on the internet.
A case in point:
– the erroneous information you received on “a baby website”.
If you accept that the Bible refers to Torah, Nevi’im and Kesuvim, or Tana”ch, then this is incorrect. (There are other books that non-Jews refer to as bible but those books are of no interest or concern when naming a baby with a holy Neshama.)
The word Sivan appears in Megillas Esther referring to a month in the calendar.
There is no connection between Sivan and bush or thorn.
(I’m trying to guess what word beginning with an S they might have confused with Sivan. Maybe “sneh”?)
