Hi Dolores, I think it is another family. I have a John the son and a Mary-mother and daughter-they came to the US and settled in Hoboken, NJ. They are related to Richard Densmer-who died in Naas, Ire in 1849 and his wife Anna Mary Giltrap- co. Wicklow-who brought the children to the US-maybe by way of Canada-the oldest daughter Anna "Maria" married Wm Early Oldfield and had her first two children there. The name is misspelled in the 1860 census as Densmore. Later info says they came over around 1852-I haven't been able to find the arrival.
