Do you mean FreeCEN ?
Searching for Charles b1869 doesnt find them - I looked for female Barnes, called Lucy or Mary (based on the Marriage page from FreeBMD)- and found the above - so if you had the correct Charles Barnes in 1896, then thats who he married - Mary Coleman and kids !
Where he is on 1901 I dont know, he's refusing to be teased out.
Any Army (Boer War) involvement to your knowledge ?
