I am researching the Serrero families from Salonica. Daniel Serrero son of Joseph was married to Gracia Cohen born in 1858. His youngest sibling named Gabriel was born in 1869. I am looking for other Serreros who would have been born in the first half of the 19th century and whose father's name would have been Joseph. The Serrero families were relatively few in Salonica. They were mainly merchants.
