I am so very sorry for your loss. I agree it would be nice to use a name in memory of the child you lost. The idea of repeating the letter Y again is good. Another idea is to select a name about the same length beginning with L and ending with A.
Finn, Kylie, (Lyra) and…..
Ayla, Lyla
Alys, Alyce
Avery
Adyson, Addyson, Addisyn, Addy
Anya, Aniya
Aliyah, Aliya
Amaya, Maya
Avery
Aylin, Adalyn
Elyse, Elyssa, Alyssa
Devyn, Dylan
L—a names
Lyla, Lena, Lina, Lara, Lora, Lola, Luna, Lila, Leia, Leah, Lilia, Livia, Lucia, Lia, Leila
Good luck with your journey.
PS. I avoided names ending in the LEE sound because I don’t think it is a good idea to repeat with a sister named Kylie.
