Margery Huckins & Sam'l Plaisted son Ricker Plaisted ?

Beverly Huckins,
Your message showed up after I did a search on one of my PLAISTED family members.
You had a lot of Huckins & Plaisted into in your message. You included info about Nancy HUCKINS who m. Samuel PLAISTED, a son of Samuel PLAISTED & Margery HUCKINS. Would you happen to have info on one of Samuel's siblings, RICKER PLAISTED (son to Sam'l & Margery)? I have that Ricker m. EUNICE PERKINS.I am looking for a couple pieces of info:
1. Ricker PLAISTED's Death:Appears that the death date would be after later than Feb. or April 1871. I surmise this due to Pension Claim Application info as follows: Age 78 at date of Claim filed - between Feb 1871 and April 20, 1871.

2. His 1st wife EUNICE PERKINS - who were her parents? I have looked for years and haven't been able to find them.

Thank you for any help you can give me on this son of Margery (Huckins) Plaisted.
