My actual name is Shengnan, pronounced SHENG-NAN, but some people call me SHEN-GAN, I am considering whether I can introduce myself by Senan if someone asked, but not sure if Senan is mature enough for an adult. You know, Senan sounds better to me, compared to SHEN-GAN.
Love this name now, took a while for me to get used to it when my nephew was born. It derives from a warrior called Senan, who became a Monk in the west of Ireland. He became famous for spreading Christianity in Ireland in the 7th century. It is thought that the river Shannon might have derived from his name.
