Robert Castell - Is this a smerged profile?

Looks like several different people are smerged into the same man.

Robert Castell was born in 1503 in Haldey, Bedfordshire, England.

His parents were Thomas Castell and Hodson Barnett.

He married Constance Haward. Together they had at least one child:

1. Martha Castell, Born 1533 in Hengrave, Suffolk, England. Married Anthony Paine.

He then married Elizabeth Hulston. Together they had at least one child:

1. Agnes Castell, Born 1529 in Somersham, Cambridgeshire, England. Married Robert March.

A Robert Castell died on June 28, 1603 in St Augustine, London, England. It does not seem likely it was this Robert.

The death source at creation of this profile Ancestry Record|lmaearlyparish|5293743 is 21 August 1603.

https://www.findagrave.com/memorial/122587838/robert-castell shows as born 1503 in Somersham, Huntingdonshire District, Cambridgeshire, England and died there on an unknown date, linked as father of Agnes (Castell) March

I will create a new profile for Robert Castell of Somersham, as that leads (in theory) to the immigrant ancestor, Henry Dow, of Hampton
