1901

Edith E Pengilly 1882 Mexico Daughter Falmouth Cornwall
Elizabeth Pengilly 1850 Gwennap, Cornwall Head Falmouth Cornwall
Ethel Pengilly 1888 Mexico Daughter Falmouth Cornwall

I believe they are all Elizabeth - but birthdates vary - and children in 1901 were all born in Mexico ..... do you know about them???
I have the images - if you would like to PM me with your email address (for privacy) I could send them and you can decide for yourself ....
Of course I haven't answered your original question but I want to make sure we have the right family - I believe the Frederick you mentioned at the beginning
is a different person.....
I also have a copy of his WW1 registration card - so let me know what you want to do and we'll go from there!!

Annie
