Not sure how this marriage fits into the Doyle family, but I feel that it must because William Henry and Elizabeth Turner were witnesses at Catherine Doyle's marriage.
Sept 14th 1862, St Thomas', Stepney
william Henry turner Bachelor Waterman and lighterman of Stepney, father Charles Turner (deceased)
Elizabeth Ann Doyle spinster of Stepney, father James Doyle, Mariner
both of full age
