Wow! I posted this last night and when I checked this morning there were no replies. But following all the activity today I think you've cracked it. Joseph Bass had (at least) 5 daughters and 2 sons (one of them Abel). According to my Bass tree these were: Elizabeth, Mary (married John Waller), Frances (married Jason Sherwood), Margaret (married Joseph Duncan), Thomas, Susanna (died in infancy) and Abel who married in England. Mary Amanda was baptized in England but when her mother died of cholera, her father brought her to his hometown of Dublin and had her baptized again at age 8. Elizabeth Bass must be the Eliza Champion of Denzille Street. It's a shame there were no early censuses because every other house on Denzille Street must have had a Bass or a Waller! I suspect he left Mary Amanda with his sister and her husband but then less than a year later, his sister died, leaving Ralph to look after Mary (with some help from his sister Harriet who survived him). The only reservation I have is was Robert a brother of Ralph and if so did he marry Eliza? Yes that is my tree on Ancestry and that is Mary Amanda's husband (my great grandfather) in my avatar picture. Is Bass Place named after the Bass family? I suspect it is. I had a walk around Denzille Street, and the place where the Champion/Waller business was and its still derelict land so I don't know what happened after it was sold. The houses on Upper Erne Street which back onto it and were once owned by RWC looked OK though but I think I was too late to ask for some rent! Thank you RootsChatters, once again I'm amazed by your ingenuity and skill. Well done!
