Trying to create my family tree, research our ancestry etc.

I have a bit started but am in need of assistance.

My grandfather's name is Theodore Wilson Porter Jr. His birth date is September 26, 1924 in Milford, Mass. to Theodore Porter & Mildred (Dove) Porter. He had a brother Thurston (Buddy). His grandfather was Arthur Porter. Arthur was a minister.

My grandfather has/had 10 children, Sylvia Jean, Allan Blaine, Brenda Joyce, Mildred Alice, Roger Ian, Debra Ivy,Percy Raymond, Thurston Robert, Pearl Nancy, Brian Craig.

I have more on the print out but it is very hard to read. Old style dot matrix printer possibly or a typewriter.

Looking for any and all information so I can trace it back to Ireland and expand it.
