Most of the trees have John, born 1808, as the son of John Bird and Mary Gadsby.
Sarah's details look correct, but I am not sure about John.
They have him born in 1774 in Packington and dying there on 2nd March 1855. The only death recorded in the area at that time, was registered in Burton upon Trent. However, he seems to be the person buried in Church Gresley on 6th March. A potter born in Shropshire c1775, he was living there with his wife, Mary, in 1841 and 1851.
Mary was buried in Church Gresley on 19th January 1847, also registered in Burton.
John and Sarah seem more likely to be the ones in Newbold Hurst, Breedon, in 1841.
On the death of Mary Bird of Worthington in 1842, it gives her place of death as Ashby-de-la-Zouch.
In 1850, there is a burial of John Bird in Breedon, and he also died in Ashby, age 72.
Their rounded down ages fit the 1841 census.
The nearest baptism was on 27th June 1779 to John and Elizabeth in Worthington. Possibly John who married Elizabeth Robinson in Breedon on 11th February 1765. A few siblings from 1767 to 1779 and possibly one in 1783.
In 2009, I took some pictures of graves in Breedon, including a few of the Bird family, and others have been added -
