Hello Mark,
May I point out an error in your tree on Ancestry please? I hope it's OK for this post to stay here and not be moved. This error is on several public trees but hopefully they will eventually be corrected.
Anthony Anstruther Wilkinson who says on the 1881 census that he was born in Limerick is not the son of Anthony J.A. Wilkinson and Marion Harriet Jones with whom he is staying in Durham. They are his aunt and uncle.
Anthony Anstruther Wilkinson was born at St Oswalds, near Limerick and parents were Thomas William Wilkinson (born approx 1822 and died in 1899, Croom, Ireland) and Helena Rosalie Brown of Wilton, Rathkeale. Helena was the daughter of William Pierce/Pearce Brown of Danesfort and Ellen Fitzgerald of Athlunkard, Limerick.
From Ireland select marriages:
Helena Rosalie Brown
Gender Female
Marriage Date 22 Apr 1845
Marriage Place 0505,Rathkeale,Limerick,Ireland
Spouse Thomas William Wilkinson
Helena died on 1st April 1860. Thomas' second wife Anne Eliza Quirk, nee Brown, was a cousin of Helena. They married at Sefton, Lancashire on 7 January 1862. His residence is St Oswalds, Ballingarry, Limerick and he states that his father is Percival Spearman Wilkinson,a clergyman. It was a double wedding and on the next page is the marriage of another relative, Henry Brown, to Ellen Quirk.
Rev P.S. Wilkinson's death in 1875 was reported in the Limerick Chronicle.
http://www.limerickcity.ie/media/Rev.%20Wilkinson.pdfThis branch of the family doesn't appear in some records about the Wilkinsons. That may be due to the scandal of Rev Anthony A Wilkinson being involved in "gross misconduct".
