Hi Frances
Thanks for all that extra info
please will you do me a big favour

please go to family search
go to search records
click on advanced search
then click on fourth down International genealogical index
then type in joshua comish in fathers name
and catherine costain in mothers name
further down the page
region -select british isles
all countries - select isle of man
then search
it brings up all the children born to that couple
it is really odd as there are children born to this couple in douglas and arbory in the same years
if you type in john comish and catherine costain
it brings up all the children they had
there are esthers around the same time in arbory to a john and catherine and a joshua and catherine
please look
thanks lesley
