I just came across this blog the other day and would like to recommend it for Follow Friday:
Grow Your Own Family Tree: Alan Stewart's UK and Ireland family history news
Most of my ancestral lines go back to the UK and Ireland, so I am always very interested in any new online sources from there!
I am particularly looking forward to the National Wills Index (http://growyourownfamilytree.wordpress.com/2010/05/04/new-records-coming-to-the-national-wills-index/) and I'm quite excited to see that Oxfordshire will be one of the first counties available! Some of my Oxfordshire ancestors surnames include: POTTER, PRESTON, HEADING, HUTTON, ANDREWS, KERSEY/CASEY, BEST, MATTHEWS, GASCOIGNE and WALWYN.
I have found Wills to be a most fascinating and useful genealogical source in my past research!
I have used the UK National Archives Documents Online many times to purchase digitised copies of Prerogative Court of Cantebury pre-1858 Wills. (http://www.nationalarchives.gov.uk/documentsonline/wills.asp?WT.hp=Wills)
Hopefully the forthcoming National Wills Index will simplify the search process for other pre-1858 UK Wills from other courts! I'm looking forward to it!
