Hi Sue,
I've looked through the St Catherines indexes for Jane & Mark's birth - Couldn't find an entry for Jane. Of Alfred's other children, there is also no entry for Charles but there is one for a George Swatten, March 1875, Auckland, 10a, 237 (perhaps they decided on a name change when they baptised him).
Elizabeth Swatton, Sept. 1876, Auckland, 10a, 181.
I checked the years 1854-1860 for Mark Shaw, there were 7 entries -
March 1856, Keighley, 9a, 173
June, 1856, Bradford Y., 9b, 147
Dec. 1858, Stockton, 10a, 69
Dec. 1858, N. Witchford, 3b, 541
March 1859, Blackburn, 83, 318
Sept. 1859, Wisbeach, 3b, 615
Dec. 1859, Stockport, 8a, 13
I'll send the information about the Swatten family via your email address over the weekend.
Regards Sue
