*Hi Belen, I am more then willing to help. The situation is this. The sources have your grandfathers surname spelled as "Semidei" and not "Semidey". This could be due to the fact that soem the spelling of some family surnames change as time passes by. Now, do you have any proof (a document) that your grandfather's surname ended with a "y" and not an "i"? If you do, you can provide me with a copy. I will also consult with a friend of mine, the author of "Historia Militar de Puerto Rico", he is from Yauco (as my family) and an expert in the matter. Don't worry we will get things right.
