My post 5 crossed with Christina's 3 and 4.

I have tried to find the census returns for 1891 and 1901 ie after Henry and Mary's Marriage 1890 but can't.

Re Wimsey's' post 18 Passenger list: Mary 28y, Martha 5y and Daniel 8. Is this correct:

MATHIAS, MARTHA MARY REES GRO Reference: 1897 J Quarter in PONTYPRIDD Volume 11A Page 470

MATHIAS, DANIEL REES GRO Reference: 1892 D Quarter in MERTHYR TYDFIL Volume 11A Page 677
Christina found Daniel in post 4

Not much help I'm sorry to say.Jill
