Hi Alan,
Thanks very much for that. Sorry I'm being a bit slow but could you point me at where the dates are wrong.
I've got the Selkirk graveyard MIs on CD from the Borders FHS, and obtained a bit of Hogg history from them - there were a lot of Hoggs around at that time.
The Thomas Hogg you mention (b. 1772, m. Agnes Angus, d. 1862) is William Hogg's father (William was born 1821). In fact Thomas and Agnes had 9 children, including the Agnes Hogg who died in 1873 but never married.
I've got William Hogg's death registration entry from SP which says William died 18 Mar 1910, was the son of Thomas Hogg and Agnes Angus (both deceased), and husband (widower) to Margaret Mcdonald.
William Hogg and Margaret Mcdonald had 5 children (Agnes b. abt 1855, William b. 1857, Thomas b. 1862, Rebecca b. 1864, and Walter b. 1866). Agnes Hogg (b. abt 1855) married Walter Lockie in 1878. I've got the marriage registration entry from SP. Walter Lockie (b. abt 1855) was the son of Hugh Lockie and Helen Fairbairn.
The Walter Lockie you mention, who married Margaret Scott and died in 1945, was the son of George Lockie and Ann Armstrong and was born abt 1864. George Lockie was Hugh's brother.
I've also noticed Agnes Angus Hogg Tait and Elizabeth Lockie Hogg in the graveyard listing but not traced them yet - more items on my "to do" list.
Regards, Chaltis
