|Letter of Shimon Sofer|
Turns out though, that the ban hadn't much effect, Bet Eked Sefarim lists several editions within the 5 years after this 1898 printing.
a friend, who is a descendant of the Chatam Sofer has supplied me with the following information:
Reb Akiva Eiger's daughter Sorel was married in תקס"ג to Reb Avrom Moshe Kalisher . and was niftar in תקע"ב they had two daughters. They both came along when she married the Chasam Sofer. one died r"l at a young age, the other one got married to Reb Yosef (Ginz) Schlesinger, who was a talmid of the Chasam Sofer too.
