Seventy-three-year-old Liz Cuccinello flew into Central Florida Thursday night where 67-year-old Christine Courtwright lives.
Courtwright says she was told as a teenager that she had an older half-sister.
She recently sent her DNA to the genealogy service My Heritage, and Cuccinello popped up as a match.
Now, after a lifetime apart, the two sisters are looking forward to a future together.
The two sisters both love cruises. So they plan to make up for lost time and take cruises together.
