Chesterton and Greenhalgh in London England- correction & more

My mistake- Alice Greenhalgh married GEORGE Chesterton, not John, but did have children Catherine (Feb. 1819) and George junior. Another daughter Harriet Chesterton was born in November 1817.

Alice may have died giving birth to George, (or to another child?) her date of death was July 30, 1826 at St. George, Hanover Square. Her husband died April 25, 1827 at Marylebone. The children Catherine and George appear to have been raised by their uncle Charles Greenhalgh born about 1788, still living in 1861, who may never have married. They lived at Hammersmith. I have no idea what happened to Harriet.

Charles Greenhalgh and his sister Alice Greenhalgh also had a brother John Greenhalgh born/baptized about March 9, 1794, I have no further info about John.

Another brother Thomas was born sometime after 1781 and died before Nov. 23, 1830 in London when his will was probated. He may never have married.

Another brother is my own ancestor James Greenhalgh born/baptized Nov. 9, 1785 at St. Pancras, who married Mary Ann Boyce August 3, 1817 at Old Church, St. Pancras.

The parents of these Greenhalgh children: Thomas, James, Charles, Alice and John were Thomas Greenhalgh and Catherine Wilder. Thomas and Catherine were married August 9th, 1781 at St. Pancras.

Thomas was dead before Catherine wrote her will- she refers to herself as a widow. Catherine's will was probated in May 1812.

I speculate that Thomas and Catherine must have been born about 1751-1761 time frame to have married in 1781.

If anyone has any additional info about any of these Greenhalgh people or about Catherine Wilder, would love to hear from you. Catherine had a brother John Wilder who apparently lived at Grosvenor Square in London. He is mentioned in the will of my ancestor James Greenhalgh (1785-1850) as his uncle.
