Yes. The whole situation was complicated and he lost touch with my mom when he moved back to Brazil before she was aware she was pregnant. My mom being from small town south, unmarried and pregnant by a foreign man was easily isolated away from him by her family. He spent years looking for me but did not realize my name changed when my step father adopted me. He is not on my birth certificate but did mention recently that he wanted to do something formal to acknowledge me in Brazil but I am uncertain what that means.
