I know its been a long time, but I have just read your message. I don't know if this is of any use to you but my Grandfather was William Inkpen who lived in Sturminster Newton Dorset married to Jane Inkpen who died and remarried a lady called Adelaide (I think). He died in the first world war.
If this helps or you ahve anything for me I would appreciate it as I am finding it hard going trying to get any leads.
