Everyone has different television delivery/provider systems. Use your television provider's schedule system to find the TLC channel number on your provider system and to learn when the show will be re-aired again.
Also, the episodes are usually available on the TLC website page sometime after they have aired. So if you don't have TLC you should be able to watch the show on your computer over the internet. You can keep up with the show in its Facebook page even if you are not on FaceBook.
And by the way, Season Two of Long Lost Family premiered on February 12. The show, which reunites long lost families, airs on TLC on Sunday nights at 9 p.m. You can catch last Sunday's episode on the website or through your cable provider's In Demand service.
