Baltimore Hebrew Congregation Synagogue

Professor Jonathan Sarna wrote about the Star of David on his book American Judaism: A History (ISBN 0-300-10197-x) that German immigrants brought the star of David with them to America, and in 1845 it was built into the windows of the new Baltimore Hebrew Congregation synagogue building (pp. 106-07).

This is a clear cut answer to the question: when did this symbol arrive to America. I had less luck finding when did this symbol arrive to Yemen (although I called up a research center of the Yemenite Jews in Natania) or to the Cochin Jews (although I called their museum in Nevatim).
