Hi Aussie Lizzie,
Here is the marriage registration information:
On 5 May 1876, John Geddis married Maggie Craig in the Ballydown Presbyterian Church in the parish of Seapatrick in the civil district of Banbridge, Co Down.
You can use this information to order an actual marriage certificate from either GROs in the island of Ireland:
1)
www.groireland.ie --- you go to this site and fill out the paper application form and post it off to there. You can get a photocopy of marriage entry for only 6 euros versus the certified copy for 10 euros. It will be about 4 weeks before you get it.
2)
www.groni.gov.uk --- you can apply online and order a certified copy for 11 pounds. You will get your copy within a week or so.
But if you were to get a reference information off the marriages indexes look up at the
www.familyulster.com and you can put this information onto the paper application form and post it off to the Belfast GRO. You will be only charged 5.50 pounds plus postage.
Next step would be asking the
www.familyulster.com to see if there is a birth registration in the indexes on your Annie Geddis as she probably was born in 1881. Or you can check the ancestryireland site's database.
Then you can try and see if you can get ahold of marriage registration on the indexes that shows any link to Annie Geddie and Lewis Houston sometimes before or in 1915--within 5 years' range.
Once you have a marriage cert, you can work backward from Lewis Houston's age and his father to identify which birth entry is his.
Good luck,
Tees
