Two women who discovered they were sisters on Facebook while separately searching for their long-lost dad have been reunited with him after 24 years—just in time for Christmas.

33-year-old Lisa McLean and 24-year-old Rebecca Parton found each other on social media while searching for their father David Riggs back in 2016.

They've since gone on to form a close sisterly bond—with Rebecca even acting as bridesmaid at Lisa's wedding last year.

After meeting, the pair failed to give up on their Facebook search for their father.

Finally, three weeks ago, their online appeal received a positive hit: Lisa received a friend request from David. She realized he was their genuine dad after he was able to identify people in childhood family photographs.

Last week, 53-year-old David traveled down from his home in Blackpool, England to meet his daughters for the first time in over twenty years.

The emotional reunion took place at Lisa's house in Nottingham, where David also got to meet his grandchildren for the first time.

They are now set to spend their first Christmas and New Year together as a complete family.

Mom-of-five Lisa, who is a carer, said: "It was just lovely… there's a lot of catching up to do—a lot of years to catch up on. The only way I can describe it, it's a bit cheesy, but I suppose it is a Christmas miracle.

Former Blackpool Pier maintenance worker David described feeling "like he'd won the lottery" and was the "happiest man in the world" after meeting his daughters.
