Help with information re photos: Yates, Lakin

[transparu]

Folks,
I am puzzling over a photograph (several, but they’re for later!).

Photo 1 is of a young couple, taken in Leicester. This is from a family source and the handwritten name on the photograph was William Yates. This was written by an elderly member of his bride’s family (Charlotte’s family) here in Australia in more recent years. I have some cause to question the name..
William Yates (b1851) married Charlotte Lakin (b1856) in Leicester on August 14 1875.  At the time of their marriage, William was 24 and Charlotte 19 years of age. Twelve days later they sailed to Australia.
My question here is “IS this William and Charlotte?” Does the nature of the photograph or their stance and clothing suggest anything about them?  Neither is wearing a wedding ring. Does anyone know the years in which this photographer operated? What is the estimate of the age of each of these two?
It IS conceivable that these two are brother and sister? Do they look related? Do their nose shapes look similar? William did have sisters who remained in Leicester (Mary Anne (b1849), Caroline (b1854) and Emma Jane (b1859). 
Photo 2 and Photo 3 are definitely Charlotte Yates (nee Lakin) taken many years later in Melbourne, Australia. The ear lobes in these two photographs do not appear to be the same as in Photo 1.  This has led me to doubt that Photo 1 IS actually William and Charlotte.
It IS still possible there are much later photographs of one of William’s brothers and nephews in family records. William and Charlotte did not have any children. There are no later, definite photographs of William (who died in1898).
I would appreciate hearing any suggestions folks may have that might help in my quest in identifying the couple in Photo 1. 

Thanks Folks.

Afraid I haven't read all of it, too much info in one go.
Pic. 1 mid-late 1890's.
Pic. 2 mid-late Edwardian.
Pic. 3 1920's poss. 30's.
Pic. 1 is a typical pose of a couple not yet married.
She has her left hand behind her indicating single.
There is a respectable distance between them with him
seated & her standing behind.
If they were siblings I would expect to see something a 
bit more personal.
So you need to look for a couple who married around 1895-1900.

Picture 1.   Their right ears are identical ( in my view) which suggests brother and sister,  cheers, Ian

their noses too, now that I look closer

I defer to Jim1's expertise at dating to narrow the period, but it is supported by references to Heawood photography at King Richard's road

Not found in 1889/1890 Directory (http://specialcollections.le.ac.uk/digital/collection/p15407coll9/id/10490/rec/15)

Earliest reference I found was 1891
(http://specialcollections.le.ac.uk/digital/collection/p15407coll9/id/20702/rec/2)

Still advertising in 1899 at that address
(http://specialcollections.le.ac.uk/digital/collection/p15407coll9/id/8375/rec/7)
and 1903
(http://specialcollections.le.ac.uk/digital/collection/p15407coll9/id/15746/rec/9)

but had moved address by 1906

Thanks Jim,

GREAT.  I appreciate this as it WILL help me look for a marriage in a family still in the UK at that time.  Unfortunately, that's unlikely to be folks closely related to my present quest - but useful all the same.
Thank you.
