Hi. I am also tracing the descendants of Manuel Arellano. But the Manuel I am searching was married to a Filomena Barreto and not Carmen. They had several children and one of them was SilvioB. Arellano. I am related to them via Manuel's wife Filomena. Silvio was born on June 18, 1915 in Manila. In 1915, Manuel's family lived in O'Donell St. (now Severino St), Sta Cruz Manila. Silvio and his other 7 siblings are listed in our family tree.
Kindly reach me at my email firstname.lastname@example.org if you are interested to communicate.
