Ralph Tomkins the emigrant https://www.wikitree.com/wiki/Tompkins-403
Biography suggests origins unknown, but nevertheless has birthplace and purported parents.
born. Monnington Hereford 1582 married in Wendover, Buckinghamshire.
His purported father is John Tompkyns https://www.wikitree.com/wiki/Thompkyns-1 b Monnington Hereford c. 1540 but died in Edlesborough ( Buckinghamshire) 1593
There is a Tompkins family from Monnington, an abstract of their pedigree is to be found in the (partially sourced) Archaeologica Cambrensis. James Tomkins and his wife Margery Kettleby are said to have had a son called John. He is the only one of the three sons that hasn't any descendants on this pedigree.
Why would a John Tomkins from the Herefordshire end up living and dying in Buckinghamshire?
Matt Tomkins researched this some years ago and there are many posts on the subject on Rootsweb and elsewhere.
This is one of the earliest posts that I found which summarised his views

A post 2 years later mentions the manifest from the Truelove in TNA which he photocopied and sent to fellow researchers.
<<My photocopy, in some clerks distinctive cursive, shows Husb[andman] Ralph Tompkins - 50, [?] Kath. Tompkins - 58, Elizabeth Tompkins - 18, Marie Tompkins - 14, and Samuel Tompkins - 22.>>

(seems even from this that Ralph 'husbandman' is an unlikely grand son of James of Monnington, his father John would be the brother of Richard, Sheriff of Herefordshire and his purported cousin James was also a Sheriff of Herefordshire and MP for Leominster )
Matthew Tomkins also posted transcriptions of the Edlesborough registers in 2000 and attempted family reconstructions of the Edlesborough Tompkins . There was no 1593 burial http://searches2.rootsweb.com/th/read/TOMPKINS/2000-01/0946751492

It seems to me Matthew Tomkins (and the list members he communicated with) found no evidence that John son of James of Herefordshire was the father of Ralph the emigrant or that he died in Buckinghamshire.
If Ralph were detached from his father John, a note could be placed on his profile to explain the lack of evidence.
It should also be possible to find other sources for the rest of this family .I wonder if John died without issue. I haven't yet found anything other than other trees for his marriage to an Ellen Stanis the marriage is said to have taken place at 'Vowchurch' . The registers not online anywhere but the earliest dates from 1670 in any case. (one Ancestry tree gave as evidence for the marriage, a London marriage licence for 1580 between a John Tomkyns embroiderer and an Ellen Stanner widow which seems to be scraping the barrel )
sorry, not been able to find any primary sources, even the Edlesborough PRs aren't online. I realise that it is mostly one persons research regurgitated but he is obviously a thorough researcher (subsequently making medieval local history his career)
