Hi
If you haven't taken this further back, this maybe a small help...
Source, Eckington PR's:
22 Sep 1754 John s. of John Leak, bap.
21 Oct 1759 George s. of John Leake, bap. According to the PR's a George Leak did marry Ann Staniforth in 1781.
20 Mar 1757 William s. of John leake, bap.
These may also be of use at some point:
10 Nov 1753 Thomas s. of John Leak, bur.
1 Nov 1771 Anne Leak d. of John & Ann, bur.
5 Dec 1771 Robert Leak s. of John & Ann, bur.
26 Aug 1803 Anne Leak, wid, bur.
9 Oct 1787 George Leak, bur.
27 Feb 1777 John Leake, bur.
