Need data on John DOLAN, b. 20 Jan. 1856, in Aughrim, Co. Galway; parents: Michael Dolan/Catherine Ford(e)-(her cemetery inscription had "Catherine Ford Dolan", but was this maiden name or middle name? John DOLAN had brothers Patrick and Thomas; sisters Ellen and Marie. Family went to Bishop Auckland, Co. Durham, England. John Dolan mar. there Margaret MULHOLLAND, dau. of John Mulholland/Julia MURRAY, on 22 May, 1880, at St Wilfred's Church. John and Margaret went to Sangamon Co., Ill. in mid-1880s. [There was a John Dolan b. in Aughrim on 19 Feb. 1855, to Michael Dolan/ Catherine GOODE. Since b. date is different, can it be same person?]. Thanks.
