If you look at the other births for the children of William Joseph Christian and Susanna(h) you will see that apart from Frank they all have mother Susanna(h) CARIN(E) or CORRIN, so must be correct.
After not finding the family in 1901:
CHRISTIAN, Susannah 33 Foxdale 1 Aug 1895 [BL's burial index]
CHRISTIAN, William Joseph 37 Foxdale 28 May 1895
With young children there should be an administration/decree naming uncle/aunt/ grandparent supervisors?
There was a Frank Christian aged 8 on the "Parisian" sailing Liverpool-Montreal, Canada, on 2 June 1898, amongst other children. Was he a Home Child?
