Hi, Luellen. The John Light profile linked to is entirely unsourced. The marriage date is correct at Ipswich, Essex, Massachusetts. Of the citations you give above, I'm not seeing any primary source documentation that shows a parental relationship with John and Dorothy (Pike) Light.
However, the last citation in the Light family history book isn't very detailed but it directs you to Old Families of Salisbury and Amesbury by Hoyt pp 231-232.
I would use Hoyt as the citation to establish the relationship for which there are several footnotes to other citations, a will, etc. I think this can also help you properly source the profile. It doesn't appear Hoyt ever found birth records for the children so it's good to give a little extra information on what does establish the relationship.
