I am researching eh family of James Orr and Margaret Geddis Orr. they had the following children: Thomas James born December 24 1858; James; May; David Henry born Feb 29 1860 (died young); William born 1863; Eliza Jane born September 1864; Ann Margaret born January 31 1867 and David Henry born May 10 1870. We descend from the youngest David Henry. There was at least one other Orr family in the Lurgan Area at the same time. Our Orr's were members of the Shankill Parish Church, the other one was a member fo the Presbyterian church. I beleive they were related buut aren't sure just how. it may be possible your Robert was anephew of our Davbid Henry. I am slowly trcking down the family but it is slow going. The records are not centeralized and difficult ot find if they are in local church registers. So far I ahve not been successful in finding someone to look those up for me. The GRO website has online birth, death and marriage records. The is also a woman who has been very kind about looking up information for me at RAOGK website. If you sent for your Roberts marriage certificate it would tell you his fathers name, that might give us a connection. The price is very reasonable about US$23.
I'd like to keep in touch and trade information. Where are you located?
