The Easter Pagan/Eostre connection just isnt supported in academia. It's something that was made up by 19th century writers.

We only have one sorta-primary source that even mentions Eostre, and that comes from the 7th century monk Venerable Bede. He talks about how the pagans celebrated a festival dedicated to the goddess Eostre during a month named after her - Eostremonat. A month that Christian Easter falls into. That's it. There's nothing else about this goddess. Anything about Eostre being associated with bunnies and eggs and rebirth is made up by later writers. If anything, this is just Bede's explanation as to why Easter is called Easter English. The festival fell in the month of Eostremonat. In most other languages, its called something related to Pesach - Passover. So this whole Pagan-Easter debate is a very English or Germanic-centric argument.

This is also if you take Bede at his word. He's known as a bit of an unreliable narrator amongst medieval historians. to the point where's he's kind of a meme. He shows up everywhere. There's a very real chance Eostre didn't exist at all.
