Searching for half-brother born in texas to mother called Becky (Rebecca), 1960's

Could you be my half-brother? The only information I have is that he was born to a woman called Becky (Rebecca) in the 1960's and given up for adoption in Texas. His birth father (my late father) was called Patrick. Becky and Patrick met in France when they were both working overseas in education but they split up and Becky went back to Texas to have her baby. Please contact me if you think this may be you.
