hi, jim, i am a mccaig not of your line but the name george peaked my interest. my great grandparents, arthur and jane mcilwaine mccaig came to the u.s. separately from county antrim, n.i. and married in nyc in 1865. they had 12 children.their 1st child, george beauregard mccaig was born in esopus, new york state in 1866.he grew up in pennsylvania with his family.
george b. is listed as missing in our family line.in my great grandmother's will, he was listed to receive an equal 1/12th share of her estate and was living in chicago.she died in shamokin in 1920.
nothing more is known concerning george b.
perhaps in researching your line, you may have come across my george beauregard mccaig.
