Stephen Griffin birth or Baptism

This is an edit. I found Stephen Griffin's and Jane (Ward) Griffin's 7 children now. With the help of this board I found one of the their children, my 3rd GGF, Nicholas Griffin, b 1817. All children were born in Swords

Since then I found the other 6 children:
John b 1810
Fanny b 1813
Mary b 1808
Matthew b 1815
Catherine b 1821
Jane b 1830

I also personally found John's family and have been emailing them. My Nichs came to Philadelphia. His John shipped to NY. Since I have all 7 children now, I am having great difficulty understanding the rest of Swords. There are some other Griffin's, not many that match Stephen's likely age, b. 1776. That gives me the idea those adults are his siblings or cousins since there are few. Anyone able to infer the other adults as either Stephen's siblings (Swords), cousins or even related?

Thanks again,

I have had great luck so far finding the parents of my GGG-Grandfather, Nicholas Griffin. I attached the marriage record of his parents, Stephen Griffin and Jane Ward. Now my goal is to find any birth record or Baptism for Stephen for purposes of verification and also to see who his parents were as well. Death records for both Stephen and Jane are also a goal so that I can complete their profiles in y family tree.

I was able to rather quickly find Jane's baptism, which helped identify her parents.

Much appreciated,
