Hello John and welcome

. Your grandfather Clifford Harper is my 1st cousin 2x removed, your post has given me some information as I did not know his exact date of birth, just the year/qtr, so thank you for that.
Clifford's mother, Mary Jane Darlow is my 2nd Great Aunt, her sister Ellen Elizabeth Darlow is my Great Grandmother. There is a photo of Ellen on page 13 of this thread and some lovely restores by Rootschat members here
http://www.rootschat.com/forum/index.php/topic,551813.0.html. You are welcome to copy the photos if you wish.
The girl in the photo with Ellen is my Aunt (still living) and I remember when she used to visit us mentioning seeing members of the Harper family in town, I seem to remember her talking about Billy Harper.
George Darlow of Sandy is my G G Grandfather too. Things get a little complicated going back to Bedfordshire and I think there may have been different spellings of the Darlow name which has complicated things - If you have had the time to read this long thread you will see what I mean

I am happy to share information I have on the family, so if there is anything you need to know just ask.
