Gladys, I popped into Toon this afternoon to T & W Archives to look at the film of those three marriages, in the hope that a jewel of info might be awaiting.
The marriage in Killingworth 21 June 1873. As you had already transcribed it
( except you missed a final "s" off Witness Burgess. lol.
Marriage by banns. Adam signed his name. Jane Lowther made a mark "X"*
( Couple of other Lowther marriages around same place/time.
On 12 May 1873 a Jane Ann Lowther, dtr of miner John Lowther married George Cowans of Dudley, son of Thomas Cowans, seaman
On 2 June 1873 Maqrgaret Lowther, 18 dtr of John, miner, married Hindrie Gilmour 24, both of Dudley, son of John Gilmour, miner.
Wits James Lowther, Margaret Purd??? )
