Currently my wife and myself are working on the genealogy of the Cabral, Mello, da Silva and de Medeiros families in the Azors.
Currently we have about 1600 names in the database and its growing fast.
we have info from about 1800 to 1840 now and are hoping to have the rest up to about 1900 by the end of march.
If you have any information about any of these families please email us, and if you would like some information do the same, and include as many relationships as you have from the persons you need, that will make it easier to identify them.
Also there is a collaboration list in familysearch.com for the name Da Silva, that you can subscribe on as well.
Thanks for helping.
