Hi Tara,
Thanks for offer. My problem is a convoluted mix of John and Margaret Fergusons.
A Margaret Ferguson appears in Griffiths Valuations 1857 as both an occupier and immediate lessor at map reference 10 in Tullyboy, Kilbride Parish, Co. Cavan. The valuation records of the Electoral Divison of Ballymachugh, parish of Kilbride 1857-1930 lists John Ferguson as occupier of map references 1 and 7 on a page that appears dated 1862. Margaret Ferguson still occupies map reference 10 but a second entry shows Robert Ferguson in a different handwriting as though he became a joint occupier about 1860. Later, about 1872 it appears that Robert becomes the sole occupier as on this page Marg. appears but is crossed out. In this time frame the name John Ferguson no longer appears. From 1880 on, the only Ferguson listed is Robert.
That Robert appears in the 1901 census, age 65. His 1834 baptism record names his parents as John and Margaret. His civil registration marriage record of 1864 names his father as John and does not indicate that his father was deceased at that time.
