Taffeta is a fabric, and I've never heard it as a female name. I have no idea on Alepatsire, sorry.
Kaitlin is a variant (and ethnically incorrect) spelling of
Caitlin:
CAITLIN f Irish, English
Pronounced: KAYT-lin
Irish form of Cateline, the Old French form of
KATHERINE. -->
Note that
Caitlin was originally pronounced coyt-LEEN.
KATHERINE f English
Pronounced: KATH-u-rin, KATH-rin
From the Greek name
Aikaterine. The etymology is debated: it could derive from the earlier Greek name Hekaterine, which came from hekateros "each of the two"; it could derive from the name of the goddess
HECATE; it could be related to Greek aikia "torture"; or it could be from a Coptic name meaning "my consecration of your name". The Romans falsely derived it from Greek katharos "pure" and changed their spelling from
Katerina to
Katharina to reflect this. The name belonged to a 4th-century saint and martyr from
Alexandria who was tortured on the famous
Catherine wheel. This name was also borne by two empresses of Russia, including
Catherine the Great, and by three of
Henry VIII's wives.
