yes, I was going to say that the Mac Cormaic family were still at Seaview Ave in 1911 and had no child named Teresa or Treasa or anything similar. Teresa/Treasa could also be a middle name or as you say, an adopted name. So the census is not looking useful. And there was no Irish census done in 1921 so it will be another 5 years before we can look at the next census release. Is there anything interesting in the Irish Times articles, do they just say where Treasa Nic Chormaic was giving a recital?
