Hi. I am a direct dewsc of nicholas Snow and Constance Hopkins through their son Joseph and am descended from other of their children also. I have their daughter Sarah married to WILLIAM Walker, not Richard... see Mayflower Descendants 5 :23; See also Mayflower Families Through 5 Generations, Vol. 6: Stephen Hopkins ; page 17 , #8: Sarah Snow, daughter of Nicholas Snow and Constance Hopkins ( daughter of Stephen of the Mayflower) married William Walker 25 Feb. 1654/5 at Eastham. William was born circa 1620 in England and died at eastham shortly before 25 Oct 1703 when his will was probated . He is probably the one of that name who arrived on the ship ELIZABETH in 1635, age 15 years. He was at Hingham in 1643. He was admitted as a freeman of the Plymouth colony on 3 june 1656. They lived near Sarah's parents on the north bank of the pond at Eastham. Williams' will was dated 8 march 1697 and mentions wife Sarah, sons William and Jabez ( 2 sons had died) and daughter Elizabeth Walker. Will was proved 25 Oct. 1703. Daughter Sarah ( wife of benjamin Lumbart) had died by that time as well. I have some information on the first 5 generations and on Nicholas as well if you would be interested. Regards, Donna Snow Crouthamel
