Thank you gilly ....
The added information was helpful. I'll summarize visually how a couple events point to the Asc/MC I was already working with and had concluded was the correct one. You are right in saying the MC figure seemed to be in late Libra/early Scorpio, as seen here in prog Mars position on the date of your company's formation in UAE. Prog Mars applies to MC within 0°04'. (Astro.com often does not calculated the MC quite accurately enough. That natal figure should be 0SCO56.) Prog Jupiter is also exactly Parallel natal Asc (0°00.5' or less).
When we go back to you and your partner's life change by buying a business in France and moving there, I used the date 29 March 2005. Progressed Jupiter had moved within 0°05' of exact Parallel to natal Asc, beginning a planetary metric for the events of the coming years (moves, etc). That progressed aspect is still active, but Jupiter's growth/expansion dynamic has moved out of the restlessness and material search to an inner one. You can also see prog Mars position in the 9th house of other countries making a culminated sextile to natal Asc (within 0°02').
In addition, your parents' birth planets confirmed this chart as opposed to one any earlier in Sagittarius. Using center England/GMT coordinates and noon times ...
Father 12 Sept 1940:
His Pluto [23N10] is nearly exactly contra-parallel your Asc, orb 0°09';
His Venus and Pluto are square your IC/MC;
His Mercury and Neptune square your Asc;
His Uranus quincunx your Asc.
Mother 21 March 1943:
Her Jupiter [22N57] is <22'> from exact contra-parallel your Asc;
Her Pluto [24N01] is <22'> from exact cp your Asc;
Her Venus +/-[11N10] is Parallel your IC 11N48;
Her N.Node 24SAG41 is trine your Asc, orb 0°22'.
If you do similar comparisons using planet positions of partners that include declinations they will show similarly close aspects.
I used all the events information you gave me and looked at both transits and progressions. So there is a lot more information than what is displayed here that went into this chart.
Cheers.
