Both Leucanthemum and marguerite are daisy like in appearance but are they the same family?

I have seen the wild flower ox eye daisy described as a marguerite - is this correct?

I have also read that leucanthemum are members of Aster family - all very confusing!
Could you provide clarification, please?

Common names can cause much confusion but "Oxeye Daisy" and "Marguerite Daisy" are related; both are in the Asteraceae family of plants, just different genus.
