This is very interesting.I am a Javier too with roots connecting to Balayan and Bauan, Batangas.
My great-great-great grandfather was a Javier who married an Luisa Orlanda.They had one child; Antonia Javier.Antonia was born in Balayan and her 2 children were born in Bauan.
Actress Nita Javier is a distant cousin of ours too.My great-uncle used to work with her back in the 1950's.There's a story that he tried to date her until he realized that they were both cousins! I should ask him the whole story sometime.
I'd like to have more information, if possible.What are the names of the 10 children? Maybe we have a connection here.
