Silas Whelan 1690

Hi all, I am trying to find any information on my 7th great grandfather Silas Whelan. From what I have found born in Dublin 1690, married Marion last name not known had a son John (my 6th Great Grandfather)born in 1715 in Dublin believed crossing into America prior to 1734. I have good track on my family back to Silas and John. Any hints or possibles appreciated.
