I have in my family tree:
Melchor Aymerich married to Josefa Espinosa de los Monteros. Their daughter Rosa Aymerich Espinosa married to Gabriel Seidel Perez de Alderete in 1840. This couple had 4 children: Luisa Seidel Aymerich, Maria de las Mercedes Aymerich, Gabriel Seidel Aymerich and Jose Antonio Seidel Aymerich.
The first Seidel family in Cuba had come from Barcelona and they were originally from Germany.
