I am sorry to hear that you've been suffering from the flu. I hope you feel better now.
Botika Boy, from what I heard, was a pharmaceutical company like Bayer-Munich now. If I'm not mistaken, this was the reason why our greatgrandfather was in the Phil. I guess he was a doctor or sales rep for the company. His name is on an old Filipino newspaper deposited in the Philippine Library of Congress. I reason I know this is I saw it myself, but unfortunately, it was written in Spanish. I saw this when I was ten years old. My mother took me there. I am very suprised that you did not know about Botika Boy.
One of our cousins, who is a international commercial pilot, went to Russelsheim, West Germany to try to get some info about the family, but to no avail.
Are you familiar with your aunts and uncles on your father's side, if not, I will gladly help out.
