There are several Island Events that could help you! Just work on keeping the villagers that you have healthy and productive, and hope for the best! If you do a search on the name "Ponui" you can find a similar story, and it turned out happily ever after!

yes but how will i get another female

as Ladyscifi said - sit tight and wait for an event that should help you out...
