Hi
Jackie,
"Ycheskil" is almost certainly a phonetic transcription of
Yechezkel or Yekhatskel (which is the Yiddish form of the name). From my own experience looking at passenger manifests, this particular name gave the immigration officers problems and spelling seems to be all over the place. The Yekhatskel in my family had his name transcribed as Chatze.
I don't think that
Pascal is an equivalent of any sort with
Yechezkel. What I think may be going on here is that his name is Yekhatskel/Yechezkel OR Khatskel, which is a more common Yiddish form seen in European records. Khatskel and Yekhatskel have a similar sounding ending to
Pascal and your ancestor may have decided to pick a name that sounded similar to the Yiddish name.
