Everything does seem to fit. When Elizabeth Ferris nee Beggs died, present at death, was her nephew Robert Beggs of 378 Oldpark Rd. On the 1943 Lennon Wylie, there is a Robert Beggs at that address, occupation welder. Elizabeth only had one nephew Robert as far as I know, born abt. 1899, the son of her brother George Augustus Chichester Beggs.
For the life of me, I cannot see John Ferris on Crumlin Rd. on Lennon Wylie in 1910. Brother John is listed as a flax dresser on both the 1901 and 1911. On Lennon Wylie, in 1910, I do find a John Ferris, flax dresser, at 12 Cupar Street. John is listed as married on both censuses but no wife present. On the 1911 census, John is on Crumlin.
Legmail St. could be Legonail, which could be a misspelling of Legoniel. I wonder if S. McIlhare is a relative, a medical person, or what, at Robert's death in 1935. As for his sister, she is listed as Eliza Ann on the 1901. On the 1911, she is still single, and a flax reeler.
I wonder if there was a sibling to Robert, also named Robert, born in 1860, who died and then our Robert was born abt 1861-62, as all other records indicate his birth to be abt 1862.
