incorrect 1881 from familysearch.org

Help! How often are these records incorrect? I have several records stating that Archabald Cameron and Jane Catherine Martin have children.... However in the 1881 search (Source Information:
Dwelling 15 Maughold St
Census Place Maughold, Isle of Man, Isle of Man
Family History Library Film 1342345
Public Records Office Reference RG11
Piece / Folio 5600 / 86
Page Number 5 )

Arch shows as Son in law????

I think this is wrong, or am I missing something???

Thanks in advance

N.B Bri.ans site confirms some of the birth certs I have.
