And Pietro, eh? Good stuff.
But WE can top that.
Fr. Gruber's great-nephew and great-niece live(d) here in Milwaukee. "Mamie" Gruber was a spinster and the choirmaster at an East Side parish for a zillion years. Her brother became a VERY wealthy spice-maker. The other grand-niece, also a spinster, was choirmaster in the Twin Cities area for a zillion years....
And Pietro, eh? Good stuff.
Yes, Pietro Yon was organist at St. Francis Xavier for about 12 years before he went to St. Patrick's Cathedral. While at Xavier, he composed "Gesu Bambino". Of course he wrote reams of both choral and organ music (and very tricky stuff too!) which is now largely gathering dust.
His brother, Constantino, was organist across town at St. Vincent Ferrer. He composed too - though output was less, and lesser known.
