hi your nmes are very similar to mine, although there seem to be many james and john galways.i go back to abt 1830 in cultra/holywood co down with a james galway. he had at least 2 children, margaret who married patrick walsh and robert who married isabella campbell.
robert and isabella settled in the docks area of belfast. thier children are: john 1862, isabella jane 1864-1866, isabella jane 1867, margaret1870, doreathea 1874-1903, james 1877-1940 and robert 1880-1882.
i can't find any trace of isabella jane and wonder if she emograted, i know my grandmother had an album of photos from america, but no-one know who of.
