First cousins once removed. > My grandchildren to my grand nieces....what are they? Your grandchildren to your sibling's grandchildren? Second cousins. > My grandchild to my daughter in laws niece...? Is your grandchild the child of the daughter-in-law, so you're asking about your son/d-i-l's child and niece? They'd be first cousins. If the grandchild is the child of a different child, there'd be no relationship between the child and the niece. Hope I understood correctly the relationships you implied. Claire K.
