I can get some of it, though possibly not much more than you already know:
Alexander Lang of Paisley had by his wife
Janet, issue -
James Lang who married? at G... near Cork? Ireland sons & daurs
Helen Lang m. Alexander Cochran of Paisley - sons & daurs
Isabel Lang m. George? Holmes lived on a farm called Yealston? in Scotland
- son & daurs
Ann Lang m. Alexander McLean - sons & daurs
Janet Lang m. Alexander Morris - sons & daurs
James Lang of Paisley, brother of above Alexander, had with other issue
John Lang, weaver, he came to Upper Canada (?), there he had 2 daurs
(inserted): an Elizabeth m. John Cline of Cornwall
born --- G.Mc.M (?)
As you can see, there's quite a bit that I wasn't sure of, but someone may be able to improve on it.
