Mazel Tov!!!!!!!!!!!
The Bais Shmuel and Maharshal both say that the mekor of Shneur is שני אור (two lights) with 2 differing stories of how it started. B"Sh says it was to name after 2 people named Meir and the Maharshal says it was to name after someone still alive named Meir (as in Meir II). Maybe name Meira to accomplish half?
