Nicholas Jacob Related to George Jacobs Sr

My 11th great-grandfather, Nicholas Jacob, was born in 1604 in Hingham, England. After looking him up on various websites, I found that he may be the brother of the famous George Jacobs, Sr. who was hanged in the Salem witch trials. However, most of the information does not meet up. George Jacobs, Sr. was born in 1620 in Bishop's Stortford, UK. According to Wikipedia, George's parents were George and Priscilla Jacobs. According to another site though, his parents were a Richard and Winifred Jacobs. I cannot find a record of Nicholas parents, but on ancestry, two people put that his parents were Richard and Winifred. I am confused as to how they found this information because I cannot find anything anywhere.

It doesn't really matter to me if Nicholas and George were brothers, but I would like to find out the truth.
