We've very recently discovered possible connections to descendants of William Yeadon & Isabel Dawson both born, we think, in Clapham, c.1695/1693. It might be that the (maternal) lineage runs as follows:Dawson-Yeadon-Jackman-Waller-Yeadon-Yeadon-Astley-Eccles.
The last two marriages took place in Blackburn; previous marriages appear to have all taken place in Giggleswick; and the Y-Y, no father/husband found.
Not having access to OPR, can anyone point us in the right direction as to how best to "authenticate" our findings and perhaps find other ancestors before William & Isabel...if we are even part way correct, please?
