MILLS Family - pre 1800 in Bucks

[Jack2023a]

Just wondering if there is any way - to track down information on baptismals etc  - I only have 2 names to go on.

MILLS Family
There were two known brothers (from a large family) - James Mills would have been born about 1785, and his brother George.  They were believed to have been born in Buckinghamshire - a place called 'Little Kimble' or around that area.

I know its not  much to go on.   Altho any help would be better than no info at all.

Cheers
