You're right! I did some checking on line 3 and I see that it was off by one generation. It should read as follows:
3-I have Elizabeth Alden m. William Pabodiel; their dau. Elizabeth Pabodie m. John Rogers; their dau. Hannah Rogers m. Samuel Bradford; their son Perez Bradford m. Abigail Belcher; their dau. Hannah Bradford m. Jabez Gay
It is perhaps of some interest to note that John Rogers was the grandson of Thomas Rogers and Samuel Bradford was the grandson of Gov. William Bradford.
