I have a limited amount of info, but here it is:
Interestingly this line went from NY to MI alright and then on to OR and there is also a McGonigal in MT also.

Zora McGonigal or McCongegal b. June 1835 and wife Maira
b, June 1838, both NY, Kids: Grove, wife Christina, moved to OR, John b. 1866, wife Mary Mattison, Jackson Co. MI, Summitt Township, Zora Jr. b. 1867, single at 42 in census. Lee b. 1879, Austin b. 1873, Archie b. 1875, married Jennie Mattison, Mary's sister, and Floyd b. 1880, I have found in 1880 and 1920 census so far. I would like to go back on Zora's line, can you help? Thanks, Althea
