greygirl,
Your Wm.Powell re. 1841 y/n??, re. 1851 bo M.Tydfil & Llanspyddid re. 1861? Do you have his marriage details?
I made a recon for him from the Lanspyddid BTs=one of 4 sisters and 3 brothers =William chr. 1792, Sept. 15 s/o William & Margaret. With further delving I came up with a problem=William s/o William Powell,farmer, buried 1814, aged 22. All events Llanspyddid P.Church.
