Hello jonw65 and ColC (Colin)
jonw65
To date I have not found a wedding document that may show witnesses. The basic information I have is from Ancestry and Find my Past.
I have, so far, not been able to locate an 1851 Census, but I do have the 1841 and 1861 (Sweady) Censuses.
I was aware of the 1863 Death of Frances Tweedy, but was not aware of the Death announcement, in the Newcastle Chronicle
ColC (Colin)
I was aware of the Baptism of James Tweedy 2 Apr 1838 but was not aware of the Castle Garth abode.
My thanks to you both for your time in looking into this for me
