Have you followed back the records of Alexander Greer, the brother in law, to see how far you can go with his genealogy?
As well the Irish had a naming pattern for the names of children. From my experience they did not follow it as slavishly as say the Scots but it can be useful. The key to making the best use of this is to make sure you have the names of ALL the children born to a couple, even the ones who may have died in infancy. Some families used the name of a child who had died, others did not.
From Wiki
A traditional naming pattern was often used by Irish parents until the later 19th century:
First son usually named for the father's father
Second son usually named for the mother's father
Third son usually named for the father
Fourth son usually named for the father's eldest brother
Fifth son usually named for the mother's eldest brother
First daughter usually named for the mother's mother
Second daughter usually named for the father's mother
Third daughter usually named for the mother
Fourth daughter usually named for the mother's eldest sister
Fifth daughter usually named for the father's eldest sister.
Looking at the list there seem to be gaps and these may be where infant children have died.
Possible gap but we don't know when they married.1. Martha Greer 1803
Gap2. Robert Greer 1806
3. Ann Jane Greer 1807-1808
4. James Greer 1809
5. Richard Greer 1810
6. Mary Greer 1811
Gap7. Margaret Greer 1814 (It may pay to find the exact date of birth) The father may have died before Margaret was born, or any time really up until 1826 though although fertility declined, it was usual to see some children though often more spaced out.
