The tree is difficult, yes, overwhelming and several mistakes are on-line. This will probably be your hardest family to figure out. My tree has lots of unconnected but definitely related Doaks. I have no idea where to look for records which would connect them. Very few of the Doak families are on-line to help out.
Any time you feel ready, I can send some transcriptions of Irish baptisms and marriages from the Lurgan area. No hurry, more will arrive by the end of the year, I think. I also have a thick stack of newspaper clippings of (Ballynagarrick and Gilford, Ireland emigrating to upstate NY) Doaks.
You can fit records together using the 1901 and 1911 Irish census, familysearch, the newspaper at "old Fulton Postcards", and the wills at PRONI which are all on-line as a guide. I can also scan or send NZ Doak info from John and Job's family.
Then you will have a firm base without everyone else's errors and guesses.
