John Nelson, b. ca 1644 m. Lydia Bartlett (second husband). Lydia was the granddaughter of Richard Warren of the Mayflower. This John Nelson was the son of William Nelson and Martha (Ford) Nelson. Page 16 of Warren (MFIP or "Pink" booklet 1991) Robert Bartlett of the "Anne" by the Mayflower Society, 2000 page 9 also states that this John Nelson married Lydia Bartlett. Her birth is listed on page 2 as daughter of Roberth Bartlett and Mary Warren. I do not have a Rogers Mayflower volume so do not know if there is a connection between surnames Nelson and Rogers.
