Sardiña and Sardiñas Family

Hi
I have info (but, still searching for more) on the Sardina Family originally from Spain, the Canary Islands, Cuba and then eventually came to the USA.My great/great/grandfather was Manuel Sardiña, son of Placido Sardina and Juana Saurez.Somewhere along the line the name had an "s" added to the end so some of the newer documents I have spells the name as
Sardiñas.I do have a lot of info on Placido Sardina's descendants.Willing to share.Marti
