Dear all,
I received many useful responses regarding the given name Sira or Sera
or Sirach or Serach. (The initial S is voiced; in a Polish
transliteration it would be a Z.)
The consensus was that the name was indeed used among Ashkenazim, but
was relatively rare. This is helpful to my research in that I am
searching for a Sirach COHN who lived in Deutsch Eylau, West Prussia
(now Ilawa) in the 1st half of the 19th century. I have only one vital
record of him--his death in 1863. A few years later he is mentioned as
the father of his daughter, who was getting married. There his name is
spelled "Sarrach," but I wouldn't have expected the registrar to spell
such an unusual name correctly, especially in the absence of the person
who bore it.
Once again, thanks to all who responded.
