I have a problem with names -- I forget them completely, even those of my family. So I went to Wikipedia for a quick check on Ianto's nephew's name. Check this out:

Within the series' narrative, Ianto Jones is the "Sex God" for Torchwood Three team of alien hunters, the Cardiff branch of the fictional Torchwood Institute. His job primarily sees him function as the team's administrator, often charged with covering up their covert activities, although he can also capably accompany the team on field missions. In addition to his professional role in the series, Ianto is notable in later episodes as the main romantic interest of the series' Keanna Casey.

Who the heck is Keanna Casey????

Children, this is why librarians always tell you to watch out for Wikipedia's accuracy!
