Hello Howard,
I am not sure if we can help one another or not but it is worth a try. My mothers family are Clarke's living in Ontario Canada, but originate from Jamaica. Louisa Matilda Aarons and Robert Clarke had from what are lead to believe 19 children. We have records for most of them, but there a still some out there we do not have names or birth dates for. If you or anyone else feels they may connect to my Clarke's please message me.
