This guy has some of the Cromhall ones abstracted
Robert Hicks (London Ironmonger) d. in 1557, mentions cousin Richard of Cromhall. This is _probably_ Richard who devised the manor of Cromhall in 1558. If we take that as fairly confident, then Richard and his brother Morgan, who are the sons of Thomas, are probably in the same generation as Robert. I find most "cousins" in wills tend to be 1st cousins, so a good working hypothesis is that Robert (d. 1557)'s father is a brother of a Thomas of Cromhall. Robert also has a brother Richard H. and a cousin Christopher H., who is not mentioned in the Cromhall wills.
So probably, there's a third brother with Thomas of Cromhall and Robert's father.
So maybe what it looks like is
- Richard of Cromhall d. 1558
- Morgan of Cromhall d. 1565
- unknown (John?)
- Robert of London, d. 1557
- Richard of ?
- unknown (Richard mercer of Boston d. 1533?)
Brother Richard's son Adrian Hix, Taylor was apparently buried in St Michael Wood Street London 27 Aug 1596
I think Christopher may be Christopher Hickes, Innkeeper of Boston, Lincolnshire, died testate 1567 (mentions son Jasper, probably later mayor of Boston)
The next thing is the Thomas & Margaret (Atwood) Hickes vs Robert Hickes (of London) suit of 1547. English Baronetage https://books.google.com/books?id=ciwUAAAAQAAJ&pg=PA341#v=onepage&f=false supposes that they're brothers, but this could also be his uncle. I don't think it's his father.
Sometime in the 1530s, we have a suit dealing with the will of a Thomas Hykces and his son Robert. http://discovery.nationalarchives.gov.uk/details/r/C7482245
The 1533 Boston, Lincs will of Richard Hyckes is probably critical. I can only find short excerpts, but it has been published in http://www.lincoln-record-society.org.uk/?publications=lincoln-wills-1532-1534. It mentions "To my brother Thomas Hyckes of Tetbury my gowne furryd "To William Hyckes off Crommell my gowne" - it has to be this family.
Thomas Hyxe of Tetbury on the 1522 militia list. http://www.tetburyfamilies.co.uk/militia-1522.html
With the 1547 suit, I kind of wonder if maybe what happened was that Robert's father died young and an uncle (Thomas) occupied some inherited lands during his minority and then had to be sued to get them back.
