I have Rookes in Halifax from about 1200 to 1555, Rookes in Bradford from 1313 to 1750, by which time he was so much invloved with Leed society that he married a Miss Leeds of Leeds and changed his name by deed poll to Rooke as a Forename, and Leeds as a surname. His land extended from Bradford past Leeds to Tadcaster. Rookes in Barnsley from 1500 to 19?? The Rookes of Halifax/Bradford moved around a lot. One branch went to the North Yorks Moors at Old Byland Another will is from Buckinhamshire, where he left money for a window in Halifax church and money to his descendants who had mostly moved over towards Bristol. Another widow, who was born in Lincoln, left money to Bradford and York churches. A number of them were dons at Oxford and I believe settled down in Glouscester. Our family appeared north of York around 1680, and I cant help believe that they are related to the Halifax/Bradford families because of the very strong pattern of Christian names. There were Rookes all around the east, south, south west and northwest of York, who now live nw of York, and who we believe we have definite connection to Bradford-Tadcaster.
I cant trace theorigins of the Barnsley family at the moment, but they appear, in the wool trade, as you would expect a second son of a sheep farmer, at just the time when the family was spreading out. Much of the data only lists the first son so I'm digging for wills etc to widen the number of possible links.
Other groups that I have not followed, even with a preliminary link, include a larger family in Linconshire around the 11-1300's. They may be the origin of the Yorkshire family. a small family between York and Scarborough around 17-1800s who have a different first name pattern. a few odd bods in Yorkshire, including one or two in Hull. Rookes in Sheffield and Derbyshire, who may also come from the LIncs family. Rookes scattered around and in London, who seem to be more part of the Yorks family thaan the others. Rookes of Devon, who I assume descend from a sailor recruited in Hull or somewhere similar. Admiral Rooke is the only one in Kent and lived closely to Chatham Docks, and I guess he was promoted in Plymouth and moved with his job to Keny (guess).
As you can see, you may have some chunks of data that I have not yet managed to find.
Your Grandfather's details might be very interesting. The main thread of the family died out in 1758, but as I say, there were many cousins, that are hard to trace, and it is the ancestors of these that I believe moved to North Yorks in 1680 or earlier.
I have contacts in Canada, New Zealand, Australia, UK and the States. They are all interested in the family, but are not too active. If you would like I will add you to the list.
Could you also let me know whether you have a genealogy program that can accept gedcom files, and I can let you havesome information I have. If you dont have this, then I can send data in MS documents/html.
