now i see you have to do with such pianos, but i have no idea why is stated on your site this genealogy-note about a Betsy Enmerich. i think she has nothing to do with the piano-builder in Vienna. from lastname Betsy he must have hungarian orgin.
so why is stated a woman with firstname Betsy which has not any connection to a hungarian lastname. the question is where is this woman born? looks have been in US and some time before the piano-builder. it has nothing to do with him, that´s all ;) her firstname is Betsy, his lastname is the hungarian Bétsy, germanized Betschi but has no connection with her firstname.
are you related to her, as you have stated her genealogy-note?
or you not related and you are thinking it is the piano-builder you stated???
of sure not the family of this piano-builder.
