I made some notes on the Carre family whilst on a different project. Unfortunatly I didnt note where I found the information - but I can tell you everything I did find was online. Try a google search for "Sir Robert Carre" and "Robert Carre Sleaford". There were several Robert Carres and some of the estates were left to brothers if there was no issue, so its worth checking them too.
"Robert Carre married the widow of the great warrior,
William, Lord Gray of Wilton, Lord Warden of the English
Marches ; and secondly, the widow of Adlard Welby, Esq., of
Gedney ; and died without issue in 1606. "
of his father I have this:
Robert Carre was thrice married : 1st, to Elizabeth Cawdron, (daughter of the King's Bayliff at Heckington) by whom he had seven children ; 2nd., to the widow Irby ; and 3rdly, to the widowed Lady Dymoke, the sister of Lord Talboys. He died in 1590, at an advanced age, and was buried in the church where his monument indicates.
Throughout his life, Robert Carre continued to reside in the
old Carre House at Sleaford ; his three sons, Bobert, Sir
William, and Sir Edward, respectively occupying the Old Place, Aswarby Park, and the old Hall at Dunsby.
Of his six surviving children, the eldest daughter, Elizabeth,
married Mr. Fairfax, of Swarby, nephew of Ralph Fairfax, the
last Prior of Kyme. Anne, the second daughter, married Robt. Whichcote, Esq., of Harpswell. Bridget married Richard Rossiter, of Somerby, and was the grandmother of Col. Sir Ed. Rossiter, M.P., George Carre, the eldest son, predeceased his father, leaving by Mary Sutton, his wife, grandniece of Lord Hussey, a son, Robert, who died young,
and a daughter, Elizabeth, who married, imprudently, Edward Sisson, Esq., and was disinherited.
Robert Carre, the second son, High Sheriff 1581, was
Founder of the Sleaford Grammar School, and of other charities at Rauceby and Aswarby. He went as Treasurer of the Army of the North, accompanied by many Lincolnshire gentlemen, to quell the rebellion against Queen Elizabeth, got up by the Earls of Northumberland and "Westmoreland.
Robert Carre married the widow of the great warrior,
William, Lord Gray of Wilton, Lord Warden of the English
Marches ; and secondly, the widow of Adlard Welby, Esq., of
Gedney ; and died without issue in 1606.
The next brother, Sir William Carre, was knighted with his
younger brother, Edward, at Belvoir Castle, Sir William died without issue in 1611, and was succeeded by his youngest brother, Sir Edward Carre, Knight, who was created a Baronet by James I, but did not long survive to enjoy that honour. He was twice married : by his first wife, Catherine Bolle, he had no family ; by the second, Anne Dyer, he left three children, Sir Robert, Rochester, and Lucy, and died in 1618 .
The widow of Sir Edward Carre, within a twelvemonth of
her first husband's death, married her countryman, Col. Hen. Cromwell, M.P., the eldest son of the veteran Royalist, Sir Oliver Cromwell, of Hitchinbroke, elder uncle of the Protector.
Sir Robert Carre, the second Baronet, on coming of age,
founded the Sleaford Hospital, A.D. 1636. In very early life he married one of the daughters and co-heirs of Sir Richard Grargrave. "
Hope that helps.
