Hi Lois,
I tried to find this family's origins a couple of years ago:

Thomas William Radcliffe (b. 1805 d. 1886) later known as Preacher Radcliffe (Wesleyan Methodist), emigrated to Cleveland with parents William Radcliffe and Bridget Lace, and Tear family, 1827, married Mary Kewish Corlett (b. 1800, d.1877) 30 Jan 1829 at Geauga Oh. and had six children: Thomas (b.1829), Charles (b. 1830). A subsequent child Mary Ann (b. 1833) is shown as born in Ohio.

Your:
"2. Thomas Radcliff family

Thomas William Radcliff (William - Bridget Lace) was baptized at KK Bride, April 20, 1805, and died at Leroy, September 16, 1886, age 81 yr. He married, in Geauga County, January 30, 1829, Mary Kewish Corlett. (Mary Kewish was the daughter of Charles and Jane (McNight) Kewish, baptized at Bride November 17, 1799. She was the widow of Thomas Corlett who died at sea, leaving her with a small child James Corlett, baptized at Bride October 5, 1823.)
Thomas and Mary Radcliff lived in Leroy."

This was as far as I got:
William RADCLIFFE marr. Bahee LACE 7 Nov. 1792 Andreas.

Six bapts for children of William Radcliffe & Bridget Lace:

William 11 May 1794
John 13 Nov 1796
Catherine 27 Aug 1799
John 3 March 1802
Thomas 20 April 1805
Charles 8 Jan 1809

Grandmother Bridget Lace, will 1813 Bride, names her daughter Bridget Radcliffe, and her grandchildren Catherine, John, & William Radcliffe. [Jim Smith]

Daniel LACE & Bridget GOLDSMITH married Andreas 4 Feb.1769.

Their children:
Bridget LACE bapt 12 NOV 1769 Andreas
Thomas LACE bapt 18 OCT 1772 Andreas

At least two possibilities for father William Radcliffe who married Bridget Lace: bapt 13 March 1768 Andreas son of William RADCLIFFE 1746-81 & Jony TEARE [William bapt 23 Nov.1746, married at aged 15/16 Jony TEARE (aged 29) dau of Eleanor, in 1762, the same day that his father Wm R married Joney’s mother Eleanor. “William Radcliffe junr & Joney Tear both of this parish married by Lic with consent of sd Wm Radcliffe’s father 24 July 1762”]

Constance Radcliffe wrote that William bapt 13 March 1768 "died in HM Service abroad".

The other possible William R. was bapt. 25 March 1763 Andreas, one of the 13 children of Wm Radcliffe [1729-1783: will] & Alice SAYLE [d.1810: will], of Ballakelly, Andreas.

Did you find burials for the parents William R. & Bridget/Bahee [Lace] Radcliffe? - Their ages at death would be very helpful.
