Hi
I am seeking information, please, regarding my great uncle, Joseph Caskey Williamson.  What I know:
- born 25 March 1897, Bovally Townland, co Londonderry to father John Williamson (1853-1934) and mother Sarah (nee McPherson)(1866-1954).
- 7 siblings, Margaretta b. 1890;  Hugh b. 1891;  Thomas b. 1893;  John b. 1895;  Herbert b. 1899; Eliza b. 1902 and Norman b. 1907.
- 1901 Ireland Census shows him age 3 living with parents and siblings in Bovally, co Londonderry.
- Church Marriage record for 2 February 1926 in the Parish of Carlisle Road, to Rebecca Livingstone Pollock.  Joseph's occupation was a Commercial Traveller.  His brother Thomas was a witness at the marriage.
- April 1954.  An Obituary for his mother Sarah Williamson in a Limavady newspaper has him as a (living) son, "Joseph C Williamson, 4 College Terrace, Londonderry, a prominent North-West businessman".
I have no other information regarding him nor his wife, Rebecca.
Any help would be much appreciated.  Thank you
