I am also looking for family roots in Spain. My great, great,great,great, grandfather was Francisco Serrano from Sastago, Aragon, Spain. He was a corporal in the Spanish army. He was born around 1700?. He accompanied Father Serra when he came to California to establish the missions. He was in San Diego in 1782. He was married to Maria Valezuela Silvas from Villa Sinaloa, Spain. Their children were Leandro and Ramona.
