Maud was my gt grandmother and she married William Chadwick in 1894 giving birth to my grandmother Emma in 1897.
I have bee able to trace Walter on the 1871 and 1881 census in Seamer but then lose track of him and others in the Jaques family do you have any further info?
I too have Sarah born 1843 and dying 1885. Her husband George never seem to be around on Census nights!
I have found Frederick Biddles on the census until 1901 but nothing for Gertrude or Cecil after 1881.

Regards

Peter
