Christine,
yes as you have probably guessed we are half siblings so "Hello" from your likkle bruvva

I have met our half sister in Northants, i used to live just a few miles from her but that was before i started researching my tree, so near and yet so far!! And yes, i now live in the Scottish Borders.
You can also add half neice to your new found family too, (i have a daughter who has just turned 16), she, along with my adoptive family still live in Lincolnshire and i still come "back home" for birthdays and xmas.
You won't be able to use the private message system yet (i think you have to make five posts on roots before it is available to you) but our Northants connection has e-mail, telephone and postal address for me should you want them at any time. For obvious reasons i won't post them here for all to see.
I have a few photographs of Jimmy and a couple of Uncle John but know next to nothing about him. We also share another uncle who died as a youngster in Lincoln in the 1920's, as far as i know there are no photographs of him though.
