How could you say the following in Turkish please?

" I last met him in January"

Thank you

Onunla en son ocakta görüşmüştüm.

Onunla en son görüştüğümde ocaktı.

this is my try

kedinero thank you

kedinero thank you

kedinero can please explain why its görüşmuştum, and not just görüştum?

Thank you so muchh

i don´t know how to explain it in english, but i will try to give you some examples.

İstanbul´a gittim (it simply mean, i went to istanbul, it can mean that you are right now traveling to istanbul)

İstanbul´a gitmiştim (it was before, it was some years ago, some months ago, some days ago) 

Birkaç yıl önce İstanbul´a gitmiştim.

Hatırlıyor musun, sana bunu vermiştim ama bir teşekkür bile etmemiştin.

i am not sure if onunla en son ocakta görüştüm is correct  , but i now görüşmüştüm is correct in that case. 

Let´s wait for native speakers 

It is similar to past perfect tense in English.

Onu gördüm means I saw her.

Onu görmüştüm means I had seen her

Both of them are correct. It is a matter of choice.

gokuyum and kedinero thank you

to meet : tanışmak (to meet someone whom you never know for first time and start to introduce each other of you)

to meet : görüşmek (to meet someone whom you know, to gather with him/her so as to spend time together or to be in dialog etc.)

One uses both of these by "ile (with)".

Onunla en son Ocak´ta görüştüm./görüştük. (I/we last met him in January. (purely: I last with him in January. / I and he last met in January.))

son = en son  : last

Ocak : January

görüş+di(simple past)+m(personal suffix)--->görüştüm (I met)
