Kenith,
www.familysearch.com seemed a good place for me to start, the last entry being a Pedigree Resource File

However that probably isnt Dromore or Albert would have mentioned it and yet?
Then still in familysearch.com, I looked for Grahams in St Helena and found Agnes Graham Birth: 17 DEC 1870 , Saint Helena, Atlantic Islands Spouse: Ellis George Family Marriage: 12 SEP 1892 St James Church, , Saint Helena, Atlantic Islands Death 25 MAR 1926 This Record submitted after 1991 by a member of the LDS Church. No additional information is available. Ancestral File may list the same family and the submitter.
UHF Ulster Historical Foundation ie
www.ancestryireland.co.uk/ If you use their search system, you will get a report which starts with Birth records for Antrim and Down, then Marriage records for Antrim and Down , then Irish ancestors being researched (members interests), then Distribution of Surnames in Ulster ( 9 counties) in the mid-1800’s [ie Mathesons Database] , then Ulster Historical Foundation Research Files and so on. You can look up say the births and you will get first names and a year and a county, only then do you have to pay to view the entry to get any more detail. In the marriage section. I have learnt to match the dates shown for husband and spouse, thus reducing the possible marriage dates, nevertheless you then need to check it out. Members interests could contain your family being researched already. The UHF has a sister website accessible ‘ History from Headstones’ here is a great first line of knowledge, you search by county and surname, again at some point you you have to pay to view the entry to get any more detail. It’s a little bit irritating when one knows they have published many of the series edited by Richard SJ Clarke . Anyway back to the main UHF search engine, you will need to look it up, but heres one group of possible extracts

Then I wondered about his army record including did he get a pension etc
