Clinch Family of North Babylon, Long Island, NY

Looking for family members who are researching the Clinch family (1900's) who live/lived in North Babylon, Long Island, NY.One name in particular, and I have no dates, is William Henry Clinch Sr., and his son William Henry Clinch, Jr. My son-in-law is William Henry Clinch III.William III believes the Clinch family came to America during the 20th century from Ireland.Both William Henry Clinch Sr. and Jr. are now deceased.Any help would be appreciated.Thank you.
