I recently discovered that Rabbi Yitzhak Ayzik GINSBURG (1780-1839) was my 6th-generation ancestor.  According to early records from Vilnius, his father was Eliyahu son of Yitzhak Ayzyk.  The larger GINSBURG family is described in a book by David Maggid, written in 1899.  The book is over 300 pages in Hebrew, well beyond my level of comprehension.  It is available online in PDF form, https://www.hebrewbooks.org/46824.

Is anybody familiar with this family who can answer some questions for me?  Please feel free to respond to me directly by e-mail at the address below.
