Thank you for your help , yes this is them on the 1880 census in Bates, no sign of Ada? they returned to the UK around 1888/89 and i have them on the 1891 census in Merthyr Tydfil, Wales.
I know that they emigrated to USA from Liverpool in 1870 as it is written on the trunk they took with them, but i can't find any documentation.
Thanks again.
