You'll need to learn a smattering of Hebrew, as I had to. The words in italics below are Hebrew.
ben = son of
bat = daughter of
ha'mechune = also known as
ha-Levi = the Levite
That makes:
Yosef son of Shlomoh also known as Zalman
Chana daughter of Shemuel Ya'acov the Levite
The marriage authorisation, which costs about £20 I believe, would clarify Joseph's place of birth. Not cheap, I know. Do you have any other way information sources?
