I posted a previous request for help about this fellow [Orphan rutherglen 1851] in March & received a suggestion about Poor Relief sources but that has been a dead end - my request to the archives met with no result, although someone searched for me, which was great.
By one of those impulses one sometimes has to look for something known to be impossible, I checked the 1841 Census for Thomas Hetherington. He was supposed to be aged 7 in April 1851 but I found a Thos Hethrington aged 0 - actually 7 months , so born Nov or Dec 1840 - in a household with no other Hetherington. This is my transcription:
1841 Census
East Clyde St, Bridgegate, Glasgow, Lanark
Household:
Robt Russell 25 Plumber b Lanark;
Elizabeth Russell 20 b Lanark;
Robt Russell 15 mo b Lanark;
Sarah Ross 30 b Outside Census County;
Sarah Inglis[?] 20 Fur Cap Maker b Outside Census County;
Elizabeth Murray 19 Fur Cap Maker b Lanark;
Thos Hethrington 7 mo b Lanark;
Anne McNab 19 [?can't decipher?] Hat Maker b Outside Census County
The census taker in that area seems to have been an orderly person - other families I look at around this address have father mother & children in order of birth, so I'm inclined to think that his mother was Elizabeth Murray. However, can anyone suggest how I can find out what was in the Kirk Sessions perhaps, or about her death before 1851 perhaps, or .....

I can find no birth record for this boy.
In 1841 there were only 59 other variations on the name Heaterington, soundexed, in Lanark. By 1851 there were still only 94 recorded. It's not a common name [like some of my others - Simpson & variations for example has 2361 in 1841 in Lanark] & I am hoping that this 7-month-old is my ancestor, the first sighting thereof.
Any clues anyone?
Thanks
