Both Saelyn and
Shaelyn look newly made-up to me, but I prefer
Shaelyn. Saelyn sounds nice but is too similar to "sailin'", *starts singing "We are sailing stormy waters, to be near you, to be free", the old
Rod Stewart hit*.
"You sought a flower and found a fruit. You sought a spring and found a sea. You sought a woman and found a soul. You are disappointed." (
Edith Södergran 1891-1923)
