Thanks for your posting about SCHUBERTs on the Niederschlesien list of 25 October 2003.
The Schuberts in your message predate my Carl Gottlieb SCHUBERT born in 1730, and I cannot see a likely connection, although it is possible that Marina SCHUBERT(born 1695) was Carl's Aunty. Nevertheless, I shall keep your information in my computer, and if I ever make a family connection, I'll contact you.
