Just got back online - sorry about the delay. You may have already discovered/uncovered the following. 1910 US Census for Ellen O'Donnell as wife of Thomas O'Donnell at 74 Canal St New Haven - children Nellie, Thomas Jr, John & Mary. Also in the household was nephew Andrew O'Donnell. Also located US World War I Draft Registration dated 12 Sept 1918 for Andrew O'Donnell 74 Canal St New Haven - make sure you look at the image bec it provides a physical description of Andrew (need to scroll to the extreme right for all of the image). Hope that this helps.
