I think we might be a generation out. My 3x great grandmother was a Margaret McGeagh born in 1798 in Tyrone, N.I. died 1848 in Cookstown. She had 2 daughters that I have found so far, Sarah b. 1822 approx and Margaret born 1826 approx in Cookstown, Co. Tyrone. Margaret McGeagh No. 1 was married to John McGeagh of Cookstown who died in 1885. He was a Grocer and Linen manufacturer and Flax merchant see links below.
My tree isn't set up yet properly but will try and organise shortly for you to have a look to see if we have McGeagh's in common. Doesn't help that they all have the same names! I haven't come across any Knipes yet in my tree.
